CD74HC377PWG4

Overview

The CD74HC377PWG4 is an octal D-type flip-flop featuring positive-edge triggering and a clock enable input. Manufactured by Texas Instruments, it belongs to the 74HC logic family and utilizes CMOS output technology with TTL-compatible inputs. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 20-TSSOP package. It provides non-inverting outputs for each of its eight circuits.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• Integrated clock enable functionality for data control
• CMOS output structure compatible with TTL input logic levels

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected component matches the required 20-TSSOP package dimensions and thermal characteristics for your design constraints.

Selection Notes

Select this component when an octal storage solution with clock enable is required. Verify that the operating voltage range of 2V to 6V aligns with the system power supply. Confirm that the 20-TSSOP package size fits the available PCB footprint and that the propagation delay specifications meet the timing requirements of the target application.

Part Context

This part is a member of the Texas Instruments 74HC series, which offers high-speed CMOS logic performance. The HC series is designed for compatibility with standard TTL logic families while providing improved noise immunity and lower power consumption compared to older logic types. The device integrates eight independent D-type flip-flops into a single package.

Replacement Considerations

Direct replacements include SN74HC377PWG4 and CD74HC377PWR. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
