SN74HC377NE4

Flip Flops Overview

The SN74HC377NE4 is an octal D-type flip-flop with clock enable, manufactured by Texas Instruments. It belongs to the HC logic series and features non-inverting outputs. The device operates on a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 160 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It supports a minimum operating temperature of -40°C and a maximum of +85°C. The component is housed in a 20-PDIP package for through-hole mounting.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops within a single integrated circuit.
• Includes a dedicated clock enable input to control data capture timing.
• Provides non-inverting outputs for direct signal transmission.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register arrays for temporary data storage
• State machine implementation in digital logic systems

Flip Flops Procurement Notes

Verify that the specific part number matches the required HC series specifications rather than LS or other variants. Confirm the PDIP-20 package type aligns with the target PCB footprint. Ensure the voltage range requirements are compatible with the 2 V to 6 V operational limits specified for this component.

Flip Flops Selection Notes

Select this component when an octal register with clock enable functionality is required. The HC series offers CMOS compatibility suitable for various logic families. Consider the 160 ns propagation delay for timing constraints. The through-hole packaging is appropriate for prototyping or specific mechanical mounting needs.

Flip Flops Part Context

This part is a variant of the SN74HC377 family, distinguished by the 'E4' suffix indicating lead-free construction. It shares functional characteristics with the standard SN74HC377N but adheres to specific environmental compliance standards. The device is designed for general-purpose digital applications requiring multiple synchronized storage elements.

Flip Flops Replacement Considerations

SN74HC377N is a parameter-equivalent alternative available from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution. Other manufacturers may offer functionally similar parts, but ensure logical family alignment.
