74AHC14 74AHCT14 Hex inverting Schmitt trigger Rev. 05 4 May 2009 Product data sheet 1. General description The 74AHC14 74AHCT14 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specied in compliance with JEDEC standard No. 7A. The 74AHC14 74AHCT14 provides six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply dened, jitter-free output signals. 2. Features n Balanced propagation delays n All inputs have Schmitt-trigger actions n Inputs accept voltages higher than V CC n Input levels: u For 74AHC14: CMOS level u For 74AHCT14: TTL level n ESD protection: u HBM EIA/JESD22-A114E exceeds 2000 V u MM EIA/JESD22-A115-A exceeds 200 V u CDM EIA/JESD22-C101C exceeds 1000 V n Multiple package options n Specied from - 40 C to +85 C and from - 40 C to +125 C74AHC14 74AHCT14 NXP Semiconductors Hex inverting Schmitt trigger 3.
