Flip Flop D-Type Bus Interface Pos-Edge 3-ST 1-Element 20-Pin SO Bulk

The 74HC/HCT374 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. The 74HC/HCT374 are 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 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 output enable is LOW, the contents of the 8 flip-flops are available at the outputs. When output enable is HIGH, the outputs go to the high impedance OFF-state. Operation of the output enable input does not affect the state of the flip-flops. The “374” is functionally identical to the “534”, but has non-inverting outputs.
