DESCRIPTION

The 74AHC/AHCT123A are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no.7A.

FEATURES

• ESD protection:

HBM EIA/JESD22-A114-A exceeds 2000 V

MM EIA/JESD22-A115-A exceeds 200 V

CDM EIA/JESD22-C101 exceeds 1000 V

• All inputs have Schmitt-trigger actions

• Inputs accept voltages higher than VCC

• For AHC only: operates with CMOS input levels

• For AHCT only: operates with TTL input levels

• Specified from−40 to +85°C and−40 to +125°C

• DC triggered from active HIGH or active LOW inputs

• Retriggerable for very long pulses up to 100 duty factor

• Direct reset terminates output pulse

• Output capability: standard (except for nREXT/CEXT).
