Flip Flops datasheet and documents for SN74LS374NSRG4

SN74LS374NSRG4

Flip Flops Overview

The SN74LS374NSRG4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the 74LS logic series. It features eight non-inverting outputs with three-state capability and positive-edge triggering. The device operates within a supply voltage range of 4.75V to 5.25V and supports surface-mount installation in a 20-SOIC package. It exhibits a maximum propagation delay of 28ns at 5V with 45pF load capacitance and provides output currents of 2.6mA (high) and 24mA (low).

Flip Flops Feature Summary

Octal D-type flip-flop architecture with single-element configuration.
Three-state outputs allowing direct bus line connections.
Positive-edge triggered data capture mechanism.
Non-inverting polarity for signal transmission.

Flip Flops Applications

Parallel-to-serial data conversion circuits.
Register storage applications in digital systems.
Buffering and driving bus lines.

Flip Flops Procurement Notes

Verify the RoHS compliance status explicitly, as historical LS variants may differ from current manufacturing standards. Confirm the specific suffix 'G4' indicates lead-free plating and environmental compliance per manufacturer documentation. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when interface compatibility with standard 74LS TTL logic families is required. The three-state output feature makes it suitable for bus-oriented designs where multiple devices share data lines. Consider the 28ns propagation delay and 5V operating voltage constraints against system timing and power specifications during the design phase.

Flip Flops Part Context

This part belongs to the Texas Instruments 74LS family of high-speed TTL logic devices. The SN74LS374 variant specifically provides octal flip-flops with three-state outputs. The 'NSRG4' designation identifies the surface-mount SOIC package and lead-free compliant manufacturing process, distinguishing it from through-hole or older packaging versions within the same functional family.
