The 74HC374N is an octal D-type Flip-Flop with positive edge-trigger and 3-state is a 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. The octal D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The 8 flip-flops 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 8 flip-flops are 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 flip-flops.
