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.
