74F273A
Datasheet
General description
The 74F273 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 CP and MR are common to all elements.
Features
- High impedance inputs for reduced loading (20µA in Low and High states)
- Ideal buffer for MOS microprocessor or memory
- Eight edge?triggered D?type flip?flops
- Buffered common clock
- Buffered asynchronous Master Reset
- See 74F377A for clock enable version
- See 74F373 for transparent latch version
- See 74F374 for 3?State version
