Product Description

The 74HC377 is an octal D-type flip-flop with clock enable. It features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. The register is enabled by a low on the clock enable (CE) input. When CE is high, the operation of the flip-flops is inhibited and their outputs remain stable, allowing for reduced power consumption during idle periods.

This device can be used in a variety of applications, ranging from temporary storage to shift registers and as control registers. The use of a master reset simplifies the design of sequential systems by instantly resetting all flip-flops during system initialization. The tri-state output feature allows for increased flexibility in bus-oriented systems by enabling multiple outputs to connect to a common bus line without interference.

Constructed with NXP's commitment to quality, the 74HC377 provides a robust and practical solution for digital storage and shift operations. Its wide operating voltage range and temperature stability make it suitable for use in industrial, consumer, and computing applications where reliable digital logic is required.
