74LV374 Octal D-type ip-op positive edge-trigger 3-state Rev. 02 14 May 2009 Product data sheet 1. General description The 74LV374 is an octal D-type ip-op 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 74LV374 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC374 and 74HCT374. The eight ip-ops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW to HIGH CP transition. When OE is LOW, the contents 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.
