NXP 74HC123D 逻辑芯片, CMOS, SMD, 74HC123, SOIC16
The is a dual retriggerable Monostable Multivibrator with reset and output pulse width control. This is high-speed Si-gate CMOS devices and are pin compatible with low-power Schottky TTL LSTTL. They are specified in compliance with JEDEC standard number 7A. Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise and fall times.
ESD sensitive device, take proper precaution while handling the device.
