Functional Description

The ABT374 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-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 individual D inputs that meet the setup and hold time requirements 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.
