SN74LS38NSR

Inverter Gates Overview

The SN74LS38NSR is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments in the LS logic series. It features open-collector outputs and is housed in a 14-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a low-level output current of 24 mA, a high-level output current of -1.2 mA, and a propagation delay of 12 ns. Static power consumption is characterized by a maximum operating supply current of 12 mA.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND buffer circuits
• Provides open-collector output configuration for wired-logic applications
• Supports standard surface-mount installation via SOIC-14 package

Inverter Gates Applications

• Open-drain bus line drivers
• Wired-OR logic implementation
• Interface driving for higher voltage loads

Inverter Gates Procurement Notes

Verify the specific suffix 'NSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the LS logic family specifications align with the target system's voltage and speed requirements before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required in a compact surface-mount form factor. Ensure the design accommodates the necessary pull-up resistors associated with open-collector outputs and verify compatibility with the 5V logic family constraints.

Inverter Gates Part Context

This part belongs to the Texas Instruments SN74LSxx series of low-power Schottky TTL logic devices. The SN74LS38 variant specifically provides buffered NAND gates with open-collector outputs, distinguishing it from standard push-pull logic families like SN74HC or SN74LS04.

Inverter Gates Replacement Considerations

Compatible substitutes include other manufacturers' SN74LS38 variants or equivalent quad 2-input NAND buffers with open-collector outputs in a 14-pin SOIC package.
