74VHC14 74VHCT14 Hex inverting Schmitt trigger Rev. 01 17 August 2009 Product data sheet 1. General description The 74VHC14 74VHCT14 are a high-speed Si-gate CMOS devices and are pin compatible with Low-power Schottky TTL (LSTTL). They are specied in compliance with JEDEC standard No. 7A. The 74VHC14 74VHCT14 provide 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 action n Inputs accept voltages higher than V CC n Input levels: u The 74VHC14 operates with CMOS input level u The 74VHCT14 operates with TTL input 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 C74VHC14 74VHCT14 NXP Semiconductors Hex inverting Schmitt trigger 3.
