OCTAL D FLIP-FLOP WITH ENABLE
The MC74F377 is a high-speed 8-Bit Register. The register consists of
eight D-Type Flip-Flops with individual D inputs and Q outputs. The common
buffered clock (CP) input loads all flip-flops simultaneously when the Enable
(E) is LOW. This device is supplied in a 20-pin package.
High Impedance NPN Base Inputs for Reduced Loading (20
μ
A in
HIGH and LOW States)
Ideal for Addressable Register Applications
Enable for Address and Data Synchronization Applications
Eight Edge-Triggered D Flip-Flops
