54F273 Datasheet Octal D Flip-flop

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: 54F 74F273 Octal D Flip-Flop Obsolete May 1995 54F 74F273 Octal D Flip-Flop.

General Description

The ’F273 has eight edge-triggered D-type flip-flops with individual D inputs and Q outputs The mon buffered Clock (CP) and Master Reset (MR) inputs load and reset (clear) all flip-flops simultaneously The register is fully edge-triggered The state of each D input one setup time before the LOW-to-HIGH clock transition is transferred to the corresponding flip-flop’s Q output All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR input The device is useful for applications where the true output only is required and the Clock and Master Reset are mon to all storage elements
