SN74HC377NSR

Flip Flops Overview

The SN74HC377NSR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features eight positive-edge-triggered D-type flip-flops with non-inverting outputs in a single package. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 20-SOIC package (0.209 inch width). It exhibits a maximum propagation delay of 27ns at 6V with 50pF load and a static current of 8µA. The component functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight independent positive-edge-triggered D-type flip-flops for parallel data storage
• Provides non-inverting outputs suitable for direct signal interfacing
• Supports wide supply voltage operation from 2V to 6V for flexible power integration

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data expansion
• General-purpose memory storage elements in digital systems

Flip Flops Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when sourcing. Confirm that the 20-SOIC footprint matches the target PCB design constraints. Ensure the selected variant meets the required operating temperature range for the intended application environment. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when an octal storage solution is required with low power consumption and wide voltage tolerance. The HC series offers standard CMOS performance compatible with various logic families. Consider the SOIC package size for space-constrained surface-mount designs. Evaluate the propagation delay specifications against the system clock requirements to ensure timing compliance.

Flip Flops Part Context

This part belongs to the SN74HC377 family of octal D-type flip-flops. It shares functional characteristics with other variants like SN74HC377N and SN74HC377DW but differs in packaging and reel specifications. The HC series represents high-speed CMOS technology, providing performance improvements over older LS or ALS logic families while maintaining backward compatibility.
