SN74HC377 - OCTAL D-TYPE FLIP-FLOPS

General Description

These devices are positive-edge-triggered octal Dtype flip-flops with an enable input.

The ’HC377 devices are similar to the ’HC273 devices, but feature a latched clock-enable (CLKEN) input instead of a common clear.

Key Features

  • Wide operating voltage range of 2 V to 6 V.
  • Outputs can drive up to 10 LSTTL loads.
  • Low power consumption, 80-µA max ICC.
  • Typical tpd = 12 ns.
  • ±4-mA output drive at 5 V.
  • Low input current of 1 µA max.
  • Eight flip-flops with single-rail outputs.
  • Clock enable latched to avoid false clocking 2.
