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 Balanced propagation delays All inputs have Schmitt-trigger actions Inputs accepts voltages higher than VCC Specified from 40 to +85 and +125 °C. DESCRIPTION The 74AHCU04 is high-speed Si-gate CMOS devices and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7A. The 74AHCU04 is a general purpose hex inverter. Each of the six inverters is a single stage. FUNCTION TABLE See note 1. INPUT nA L H Note 1. H = HIGH voltage level; L = LOW voltage level.
