Description

The 74HCT423PW is a high-speed Si-gate CMOS semiconductor device which belongs to the Multivibrators product category. It is pin compatible with Low power Schottky TTL (LSTTL) and is specified in compliance with JEDEC standard no. 7A. This device is DC triggered from active HIGH or active LOW inputs and features a retriggerable option for very long pulses up to 100% duty factor. The device also has a direct reset that terminates output pulses and Schmitt-trigger action on all inputs except for the reset input. It is designed to comply with JEDEC standard no. 7A and has ESD protection. The device is specified to operate from -40°C to +85 °C and from -40°C to +125°C.
