SN74HCT273 - Octal D-Type Flip-Flops

General Description

These devices are positive-edge-triggered D-type flipflops with a common enable input.

The ’HCT273 devices are similar to the ’HCT377 devices, but feature a common clear enable (CLR) input instead of a latched clock.

Key Features

  • Operating voltage range of 4.5V to 5.5V.
  • Outputs can drive up to 10 LSTTL loads.
  • Low power consumption, 80µA maximum ICC.
  • Typical tpd = 12ns.
  • ±4mA output drive at 5V.
  • Low input current of 1µA maximum.
  • Inputs are TTL-voltage compatible.
  • Contain eight D-type flip-flops.
  • Direct clear input 2.
