CD74HC273 - Octal D-Type Flip-Flop

Description

The ’HC273 and ’HCT273 high speed octal D-Type flip-flops with a direct clear input are manufactured with silicon-gate CMOS technology.

They possess the low power consumption of standard CMOS integrated circuits.

Features

  • Common clock and asynchronous controller reset.
  • Positive edge triggering.
  • Buffered inputs.
  • Fanout (over temperature range).
  • Standard outputs: 10 LSTTL loads.
  • Bus driver outputs: 15 LSTTL loads.
  • Wide operating temperature range:.
  • 55℃ to 125℃.
  • Balanced propagation delay and transition times.
  • Significant power reduction compared to LSTTL Logic ICs.
  • HC types:.
  • 2 V to 6 V operation.
  • Hi.
