The SN74HC139 is a device designed for high-performance memory decoding or data routing applications that require very short propagation delay times. It is suitable for high-performance memory systems and can minimize the effects of system decoding. When used with high-speed memories utilizing a fast enable circuit, the delay time of this decoder and the enable time of the memory are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible.

This datasheet provides detailed information on the SN74ALVCH162344, including its operating voltage range, output current, and packaging.

BD9739KN, BD9740KN are 7-channel switching regulators with built-in FETs designed for use in digital still cameras. Their features include wide supply voltage range, high-precision reference voltage, selectable step-up/step-down mode, built-in load switch circuit, support for inverting circuit, support for constant-current LED drive etc.

BD9763FVM is a 1-channel high efficiency step-up switching regulator from ROHM. It has a max switching frequency of 1.2MHz, high accuracy reference voltage (2.5V±1.0%), establish maximum duty cycle internally, CTL/SS terminal for both stand-by and soft-start function (soft-start time can be set by external capacitor) etc.

This document introduces the BD9850FVM and BD9851EFV, two switch power supply controllers, which are respectively suitable for 1-channel and 2-channel switch power supply, with a maximum switching frequency of 2 MHz and 3 MHz, high-precision reference voltage, undervoltage lockout and thermal shutdown functions, and MSOP8 and HTSSOP-B20 packages.

The BD9853AFV is a 2-channel synchronous DC/DC controller that can operate at a maximum switching frequency of 2MHz, enabling the use of a smaller external coil than conventional lower-frequency switching regulators. This makes the BD9853AFV a suitable choice for downsizing applications.

The BD9870FPS is a single-channel step-down switching regulator that integrates a Pch MOSFET capable of PWM operation at 900kHz, enabling use of a smaller coil, as well as circuitry that eliminates the need for external compensation – only a diode, coil, and ceramic capacitor are required – reducing board size significantly.

BD6046GUL is a charge protection IC with built-in FET negative voltage protection produced by ROHM. It can prevent negative voltage caused by USB reverse insertion without any additional components, and also has overvoltage protection, overcurrent protection, temperature protection and other functions.

BD63536FJ is a high-frequency switching regulator produced by ROHM. It has a rated voltage of 3V and uses a SOP-J8 package. The regulator features a 1% reference voltage accuracy and a 4% overcurrent protection function, and has a variety of built-in protection circuits, which can be used in laser printers, multifunction printers and personal computers.

The SMT15C series is a new high density open-frame, non-isolated converter for space sensitive applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8Vdc) and offers a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 15 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to the 5 V maximum. Typical efficiencies for the models are 89% for the 5 V input version and 91% for the 12 V input version. The series offers remote ON/OFF and overcurrent protection as standard. With full international safety approvals including EN60950 and UL/cUL60950, the SMT15C reduces compliance costs and time to market.

SML70020 Series is a series of rectangular bicolor LED products with forward voltage VF of 1.9 to 2.0 V, maximum forward current IF of 10 mA, and peak wavelength λP of 630 to 560 nm.
