SN54HC377, SN74HC377 SCLS307D – JANUARY 1996 – REVISED MAY 2022 SNx4HC377 Octal D-Type Flip-Flops With Clock Enable 1 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 Applications Buffer/storage registers Shift registers Pattern generators 3 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.
