INTEGRATED CIRCUITS DATA SHEET 74AHC373; 74AHCT373 Octal D-type transparent latch; 3-state Product specification Supersedes data of 1998 Dec 11 File under Integrated Circuits, IC06 1999 Nov 23 Philips Semiconductors Product specification Octal D-type transparent latch; 3-state 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 Common 3-state output enable input Functionally identical to the ‘533’, ‘563’ and ‘573’ 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. DESCRIPTION The 74AHC/AHCT373 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. QUICK REFERENCE DATA Ground = 0 V; Tamb = 25 °C; tr = tf ≤ 3.0 ns. 74AHC373; 74AHCT373 The 74AHC/AHCT373 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. A Latch Enable (LE) input and an Output Enable (OE) input are common to all latches. The ‘373’ consists of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at the Dn inputs enters the latches. In this condition the latches are transparent, i.e. a latch output will chan...
