Product Summary

The 74HCT273 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The 74HCT273 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (pin CP) and master reset (pin MR) inputs load and reset (clear) all flip-flops simultaneously. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop.
