74HC377FP-E

Overview

The Renesas Electronics Corporation 74HC377FP-E is an octal D-type flip-flop with enable, belonging to the HC/UH logic series. It utilizes a 16-pin SOP (Small Outline Package) for surface-mount installation. The device operates within a supply voltage range of 2V to 6V and supports a clock frequency up to 50MHz. Key electrical parameters include a typical propagation delay of 13ns at 50pF load, a maximum static current of 4µA, and output currents capable of driving 10 LSTTL loads. It functions as a positive-edge triggered storage element suitable for high-speed digital applications.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Positive-edge clock triggering with enable input control for data transfer
• High-speed operation with low propagation delay characteristics
• Wide operating voltage range supporting diverse system power requirements

Applications

• Temporary binary information storage between processing units
• Input/output interface buffering for indicator units
• Data register applications in general-purpose system control
• Parallel-to-serial conversion circuits requiring edge-triggered latching

Procurement Notes

Verify that the suffix 'FP' corresponds to the specific 16-pin SOP package variant required for your PCB layout. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides official datasheets matching the exact part number to avoid pinout mismatches. Check for any specific handling instructions related to surface-mount technology assembly processes.

Selection Notes

Select this component when an octal D-type flip-flop with enable functionality is required in a surface-mount form factor. The HC series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the 2V to 6V operating range compatibility with your system's voltage rails. Evaluate the 13ns propagation delay against your timing constraints for high-speed data processing tasks.

Part Context

This component is part of the HD74HC377 family, which includes octal D-type flip-flops with enable inputs. It shares functional similarities with other manufacturers' 74HC377 variants but is distinguished by its specific packaging and Renesas manufacturing specifications. The HC series is widely used in digital electronics for data storage and transfer operations.

Replacement Considerations

Compatible substitutes include SN54HC377 from Texas Instruments and HD74HC377 from Hitachi Semiconductor. Verify package dimensions and pinout compatibility before substitution. Ensure equivalent electrical characteristics such as voltage range and propagation delay are met.
