74AHC374 74AHCT374 Octal D-type ip-op positive edge-trigger 3-state Rev. 03 12 June 2008 Product data sheet 1. General description The 74AHC374 74AHCT374 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. 7-A. The 74AHC374 74AHCT374 comprises eight D-type ip-ops featuring separate D-type inputs for each ip-op and 3-state outputs for bus oriented applications. A clock input (CP) and an output enable input (OE) are common to all ip-ops. The eight ip-ops will store the state of their individual D inputs that meet the set-up and hold times requirements for the LOW-to-HIGH CP transition. When OE is LOW the content of the eight ip-ops is available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the ip-ops. 2.
