CD54HCT273 Octal D-Type Flip-Flop

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. Information at the D input is transferred to the Q outputs on the positive-going edge of the clock pulse. All eight flip-flops are controlled by .

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
• HCT types:
  – 4.5 V to 5.5 V operation
  – Direct LSTTL input logic compatibility, VIL = 0.8 V (max), VIH = 2 V (min)
  – CMOS input compatibility, .
