• EXAR SP6651A Manual

  SP6651A is a 800mA synchronous buck regulator which is ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input

• EXAR SP481R/SP485R 1/10th Unit Load RS-485 Transceiver Manual

  The SP481R and SP485R are pin-to-pin equivalent with our existing SP485 product and contain enhancements such as higher ESD tolerance and high receiver input impedance. The higher receiver input impedance allows for connecting over 400 transceivers on a single transmission line without degrading the RS-485 driver signal. Each device is packaged in an 8-pin plastic DIP or 8-pin narrow SOIC package. The SP481R offers a shutdown feature via the enable pins which will reduce the supply current (ICC) below 0.5µA typical.

• EXAR ST16C550 UART WITH 16-BYTE FIFO s handbook

  The ST16C550 is a universal asynchronous receiver and transmitter with 16 byte transmit and receive FIFO. It operates at 2.97 to 5.5 volts. A programmable baud rate generator can select transmit and receive clock rates from 50 bps to 1.5 Mbps. The ST16C550 is an improved version of the NS16C550 UART with higher operating speed and lower access time.

• EXAR -XR16L2450 2.25V TO 5.5V DUART handbook

  The XR16L2450 is a dual universal asynchronous receiver and transmitter (UART) from Exar Corporation with lower operating voltage and 5 volt tolerant inputs.

• EXAR SP6132 Manual

  The SP6132 is a wide input, 300KHz synchronous PWM controller optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12V step down with 5V used to power the controller. This lower VCC voltage minimizes power dissipation in the part. The SP6132 is designed to drive a pair of external NFETs using a fixed 300kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output short circuit protection. The SP6132 is available in the cost and space saving 10-pin MSOP.

It features a watchdog timer, a µP reset and backup- battery switchover, and power-failure warning; a complete µP monitoring and watchdog solution.

• EXAR XR16M770 Manual

  The XR16M770 is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with 64 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 16 Mbps at 3.3V, 12.5 Mbps at 2.5V and 7.5 Mbps at 1.8V with 4X data sampling rate.

• EXAR XR-2211A Manual

  The XR-2211A is a monolithic phase-locked loop (PLL) system especially designed for data communications applications. It is particularly suited for FSK modem applications. It operates over a wide supply voltage range of 4.5 to 20V and a wide frequency range of 0.01Hz to 300kHz. It can accommodate analog signals between 10mV and 3V, and can interface with conventional DTL, TTL, and ECL logic families. The circuit consists of a basic PLL for tracking an input signal within the pass band, a quadrature phase detector which provides carrier detection, and an FSK voltage comparator which provides FSK demodulation. External components are used to independently set center frequency, bandwidth, and output delay. An internal voltage reference proportional to the power supply is provided at an output pin. The XR-2211A is available in 14 pin packages specified for
