SN74AHC132DRE4

Overview

The SN74AHC132DRE4 is a quadruple positive-NAND gate featuring Schmitt-trigger inputs, manufactured by Texas Instruments. It belongs to the AHC logic series and operates within a supply voltage range of 2 V to 5.5 V. The device provides four independent gates with two inputs each, housed in a 14-pin SOIC package. Key electrical characteristics include a propagation delay of 5.5 ns at 5 V, low-level output current of 8 mA, and high-level output current of -8 mA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent NAND gates with Schmitt-trigger inputs for noise filtering
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides robust output drive capability with 8 mA sink and source currents

Applications

• Signal conditioning and waveform shaping in noisy environments
• Debouncing mechanical switches and contacts
• Pulse width modulation signal processing

Procurement Notes

Verify the specific ordering suffix DRE4 corresponds to the SOIC-14 surface-mount package and tape-and-reel configuration. Confirm RoHS compliance status as indicated in official documentation. Ensure the component meets the required industrial temperature range specifications for your application environment before finalizing procurement.

Selection Notes

Select this component when Schmitt-trigger action is required to eliminate noise on slow-rising input signals. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Verify that the 5.5 ns propagation delay meets system timing requirements and that the 2 V to 5.5 V supply range aligns with available power rails.

Part Context

This part is part of the SN74AHC132 family of quad NAND gates with Schmitt triggers. The 'D' suffix denotes the SOIC-14 package type, while 'RE4' indicates the reel packaging and lead-free/RoHS compliant variant. It serves as a digital logic interface component for converting analog-like signals into clean digital pulses.

Replacement Considerations

Compatible substitutes include SN74AHC132DR (standard reel) and SN74AHC132D (tube packaging). Cross-reference with SN74AHCT132DRE4 if 5 V only operation is acceptable and TTL-compatible input thresholds are needed.
