Pin Descriptions

Functional Description

The ’FCT374 consists of eight edge-triggered flip-flops with

individual D-type inputs and TRI-STATE true outputs. The

buffered clock and buffered Output Enable are common to all

flip-flops. The eight flip-flops will store the state of their indi-

vidual D inputs that meet the setup and hold time require-

ments on the LOW-to-HIGH Clock (CP) transition. With the

Output Enable (OE) LOW, the contents of the eight flip-flops

are available at the outputs. When OE is HIGH, the outputs

are in a high impedance state. Operation of the OE input

does not affect the state of the flip-flops.
