SN74LS377DW

Flip Flops Overview

The SN74LS377DW is an octal D-type flip-flop from the Texas Instruments 74LS series, housed in a 20-SOIC surface-mount package. It features eight non-inverting outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device exhibits a propagation delay of 27 ns, with output current capabilities of -400 µA at high level and 8 mA at low level. It functions reliably across a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains eight independent positive-edge-triggered D-type flip-flops for parallel data storage
• Provides standard TTL-compatible input and output logic levels
• Delivers non-inverting output signals synchronized with the clock edge

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register applications
• Shift register configurations

Flip Flops Procurement Notes

Verify that the specific order matches the SN74LS377DW suffix indicating the SOIC-20 surface mount package. Confirm the manufacturer is Texas Instruments to ensure component authenticity. Check RoHS compliance status as required by project specifications. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Flip Flops Selection Notes

Select this component when eight-bit synchronous storage with TTL compatibility is required in a surface-mount design. Compare against the SN74LS377N if through-hole mounting is preferred instead. Consider the SN74HC377DW for lower power consumption or wider voltage ranges, noting the differences in logic family characteristics and switching speeds.

Flip Flops Part Context

This part belongs to the SN74LS377 family of octal D-type flip-flops. It shares functional similarities with other members like the SN74LS377N but differs in physical packaging. The LS series indicates Low-power Schottky technology, offering a balance between speed and power dissipation compared to standard TTL variants.

Flip Flops Replacement Considerations

The SN74LS377DWR serves as a reel-packaged alternative from the same manufacturer. The SN74LS377NE4 is a lead-free variant of the through-hole version.
