SN74HCT377DWR

Flip Flops Overview

The SN74HCT377DWR is an octal D-type flip-flop manufactured by Texas Instruments, featuring a clock enable function. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-SOIC surface-mount package. The device exhibits a propagation delay of 30 ns, with output drive capabilities of -4 mA for high-level and 4 mA for low-level currents. It supports non-inverting outputs and functions across an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Clock enable functionality allowing precise control over data latching operations
• CMOS output structure ensuring compatibility with TTL input logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the HCT logic family voltage requirements align with the system's 5V power rails. Ensure the SOIC-20 footprint matches the PCB design constraints and thermal management specifications.

Flip Flops Selection Notes

Select this component when an octal storage solution with clock enable is required for 5V logic systems. The HCT series ensures direct compatibility with standard TTL inputs without additional level shifting. Consider the 30 ns propagation delay against system timing requirements and verify the 20-SOIC package fits the available board space.
