SN74AHCT132NSR

Overview

The SN74AHCT132NSR is a quadruple positive-NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74AHCT logic family, featuring Schmitt-trigger inputs for noise immunity and high-speed operation. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 14-pin SOIC surface-mount package. Key electrical characteristics include low static power consumption and defined propagation delays suitable for digital signal processing applications requiring precise timing control.

Feature Summary

• Integrates four independent NAND gates with Schmitt-trigger input thresholds to filter noisy signals.
• Compatible with standard 5-V CMOS operating voltages while maintaining AHCT performance levels.
• Provides robust output drive capabilities suitable for interfacing with various digital loads.

Applications

• Digital signal conditioning in communication systems
• Clock generation circuits requiring hysteresis
• Pulse width modulation signal processing

Procurement Notes

Verify the specific suffix NSR indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range meets system requirements as specified in the datasheet. Cross-reference ordering information with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when 5-V CMOS compatibility is required alongside the noise rejection benefits of Schmitt triggers. Compare propagation delay specifications against system timing constraints. Evaluate package size constraints relative to available PCB real estate. Consider power dissipation limits under maximum load conditions during thermal analysis.

Part Context

This part is part of the broader 74AHCT series, designed to bridge HC and HCT logic families. It offers improved speed over standard HCT devices while maintaining pinout compatibility. The SN74AHCT132 variant specifically focuses on NAND functionality with enhanced input characteristics for demanding digital environments.

Replacement Considerations

SN74AHCT132N is a direct pin-compatible alternative in a different package format. SN74HC132 may serve as a substitute if lower speed and higher voltage tolerance are acceptable. Verify logical equivalence and electrical parameters before substituting any other NAND gate variants.
