CD74HC273 Overview
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.
Key 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 – High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
