The MM74HC04 is a triple buffered inverter that utilizes advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. It has high noise immunity and the ability to drive 10 LS-TTL loads.

This document introduces the features of the NM93C06LZ series of chips, including 256, 1024, 2048, and 4096 bits of storage capacity. They use CMOS non-volatile electrically erasable memory, divided into 16, 64, 128, 256 16-bit registers. They are manufactured using National Semiconductor’s floating-gate CMOS process for high reliability and low power consumption. These memory devices are available in both SO and TSSOP packages for small space considerations. The serial interface that operates these EEPROMs is MI- CROWIRE compatible for simple interface to standard mi- crocontrollers and microprocessors. There are 7 instruc- tions that control these devices. Read, Erase, Write Enable, Erase, Erase All, Write, Write All, and Erase-Write Disable. The ready-busy status is available on the DO pin to indicate the completion of a programming cycle.

The LM2673 is a 3A step-down switching regulator from Texas Instruments with a maximum output current of 3A and high efficiency.

LM4915 is a low-power, high-performance audio power amplifier from Infineon. It is mainly used in mobile phones and other portable audio devices. The chip uses pseudo-differential amplification technology, has input capacitance matching function and low voltage shutdown function. LM4915 can provide 280mW of peak power and 90mW of average power to a 32 ohm load.

LM5071 PoE PD controller is an integrated circuit that can power devices connected to PoE networks. It can be powered by a 12V AC adapter or an Ethernet network.

The LMH664XEP family true single supply voltage feedback amplifiers offer high speed (130MHz), low distortion (-62dBc), and exceptionally high output current (approximately 75mA) at low cost and with reduced power consumption when compared against existing devices with similar performance. Input common mode voltage range extends to 0.5V below V- and 1V from V+. Output voltage range extends to within 40mV of either supply rail, allowing wide dynamic range especially desirable in low voltage applications. The output stage is capable of approximately 75mA in order to drive heavy loads. Fast output Slew Rate (130V/µs) ensures large peak-to-peak output swings can be maintained even at higher speeds, resulting in exceptional full power bandwidth of 40MHz with a 3V supply. These characteristics, along with low cost, are ideal features for a multitude of industrial and commercial applications. Careful attention has been paid to ensure device stability under all operating voltages and modes. The result is a very well behaved frequency response characteristic (0.1dB gain flatness up the 12MHz under 150Ω load and AV = +2) with minimal peaking (typically 2dB maximum) for any gain setting and under both heavy and light loads. This along with fast settling time (68ns) and low distortion allows the device to operate well in ADC buffer, and high frequency filter applications.

74VHC943 is a full duplex low speed modem for data communication over telephone lines and other narrow bandwidth channels. It provides a 300 baud bidirectional serial interface and is Bell 103 compatible. The 74VHC943 utilizes advanced silicon-gate CMOS technology. Switched capacitor techniques are used to perform analog signal processing. The modulator section contains a frequency synthesizer and a sine wave synthesizer, producing a phase coherent frequency shift keyed (FSK) output. The line driver and hybrid section are designed to facilitate connection to a 600X telephone line, they can perform two to four wire conversion and drive the line at a maximum of b9 dBm. The demodulator section incorporates anti-aliasing filters, a receive filter, limiter, discriminator, and carrier detect circuit. The nine-pole receive filter provides 60 dB of transmitted tone rejection. The discriminator is fully balanced for stable operation.

The CLC5506 is a low-noise programmable gain amplifier for use in cellular base stations, WLL, radar and RF/IF subsystems where gain-control is required to increase the dynamic range. The CLC5506 allows designers to compensate for manufacturing component tolerances and temperature variations in receiver front ends. Maximum amplifier gain is set at 26 dB . A three-line MICROWIRE serial interface allows 16 dB of attenuation from the max gain setting in precise 0.25 dB steps. The CLC5506 uses a differential input and output, allowing large output swings on a single 5V rail. The differential output is well suited for impedance matching networks driving SAW filters or directly driving differential input analog to digital converters (ADC). The differential output also makes it possible to drive transformers allowing designers the ability to match a wide variety of transmission lines. The output amplifier has excellent output drive with low distortion. Digital control of the CLC5506 is accomplished using MICROWIRE Interface. Data Out and a Load Enable are incorporated so that more than one CLC5506/channel may be programmed per system. The CLC5506 maintains a 600MHz performance bandwidth over its entire gain and attenuation range from +10dB to +26dB. Gain control is divided into 64 equal steps of 0.25dB and is dB-linear. Output drive and distortion performance are excellent; In a 50Ω system, the third-order output harmonic distortion is less than -80dBc.
