SN74LS378NSR

Flip Flops Overview

The SN74LS378NSR is a hex D-type flip-flop manufactured by Texas Instruments in the LS logic series. It features six independent D-type flip-flops with positive-edge triggering, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Key electrical characteristics include a propagation delay of 27 ns at 5 V, a low-level output current of 8 mA, and a high-level output current of -400 uA. It functions reliably across an operating temperature range from 0°C to +70°C.

Flip Flops Feature Summary

• Contains six independent positive-edge triggered D-type flip-flops for parallel data storage
• Compatible with standard TTL logic families for input and output interfacing
• Designed for surface-mount installation using a 16-lead small-outline integrated circuit package

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage elements in logic systems

Flip Flops Procurement Notes

Verify the specific suffix 'NSR' corresponds to the reel packaging format required for your assembly line. Confirm that the LS logic family specifications meet the timing and drive requirements of your target application. Ensure compatibility with existing inventory management systems regarding the manufacturer's part numbering conventions.

Flip Flops Selection Notes

Select this component when a compact solution for storing six bits of data is required without individual clock enable lines. The LS series offers a balance of speed and power consumption suitable for general-purpose digital designs. Consider the SOIC package dimensions for PCB layout constraints and thermal dissipation needs during the design phase.

Flip Flops Part Context

This component belongs to the SN74LSxx series of bipolar logic devices produced by Texas Instruments. The SN74LS378 specifically provides hex D-type flip-flops, distinguishing it from octal variants like the SN74LS377 or latches such as the SN74LS75. It serves as a fundamental building block for sequential logic circuits requiring multiple independent storage elements.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify that any substitute maintains the 16-SOIC footprint and identical electrical parameters to ensure seamless integration without redesigning the host circuit board.
