General description
The 74LVT273 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.
This device 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 independent of the clock or data inputs by a LOW voltage level on the MR input. The device is useful for applications where only the true output is required and the CP and MR are common elements.
