SN74S38NSR

Inverter Gates Overview

The SN74S38NSR is a quad 2-input positive-NAND buffer manufactured by Texas Instruments in the SN74S series. It features open-collector outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides a low-level output current of 60 mA and exhibits a propagation delay of 10 ns. It is housed in a 14-pin Small Outline Package (SOIC) with a surface-mount installation style. The operational temperature range spans from 0°C to +70°C.

Inverter Gates Feature Summary

• Quad 2-input positive-NAND buffer configuration

• Surface-mount SOIC-14 package

Inverter Gates Applications

• High-speed digital logic processing
• Open-drain bus line drivers
• General-purpose NAND buffering

Inverter Gates Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when ordering. Confirm the SN74S series designation matches the required Schottky TTL performance specifications. Ensure the SOIC-14 footprint aligns with the target PCB design. Validate that the open-collector output type suits the application's pull-up requirements. Check RoHS compliance status through official manufacturer documentation.

Inverter Gates Selection Notes

Select this component when high-speed switching and high sink current are required. The open-collector outputs allow for wired-OR connections and level shifting. Compare propagation delay and power consumption against other logic families if speed is critical. Ensure the operating voltage remains within the specified 4.75 V to 5.25 V range for reliable operation.

Inverter Gates Part Context

This part belongs to the SN74S family, known for Schottky clamping to prevent saturation and improve switching speeds. It serves as a high-performance alternative to standard TTL logic. The SN74S38 variant specifically provides buffered NAND functionality with open-collector outputs, distinguishing it from standard push-pull outputs found in other logic gates.

Inverter Gates Replacement Considerations

The SN74LS37NSR offers similar logical function but uses LS technology with lower current drive and different electrical characteristics. Verify compatibility regarding output current capabilities and propagation delays before substitution.
