Description

Features, Applications

The 'ABT273 has eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common 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 common to all storage elements. Buffered common clock Buffered, asynchronous Master Reset See 'ABT377 for clock enable version See 'ABT373 for transparent latch version See 'ABT374 for TRI-STATE � version Output sink capability of 48 mA, source capability 24 mA Guaranteed latchup protection High impedance glitch free bus loading during entire power up and power down cycle Non-destructive hot insertion capability Disable time less than enable time to avoid bus contention Standard Microcircuit Drawing (SMD) 5962-9321701
