SN74AHCT132BQAR

Overview

The SN74AHCT132BQAR is a quadruple positive-NAND gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features low power consumption with a maximum ICC of 10 µA. The device provides ±8 mA output drive at 5 V and includes temperature-compensated threshold levels for high noise immunity. It utilizes a WQFN-14 package (BQA) measuring 3 mm × 2.5 mm, suitable for surface-mount applications.

Feature Summary

• Schmitt-trigger architecture enables clean jitter-free outputs from slow input transitions
• TTL-compatible CMOS inputs provide reduced voltage thresholds for system interfacing
• Balanced push-pull outputs support similar sourcing and sinking current capabilities

Applications

• Enable or disable digital signals
• Controlling indicator LEDs
• Translation between communication modules and system controllers

Procurement Notes

Verify the specific BQA package designation and lead finish details against the latest Orderable Addendum. Confirm that the operating temperature range aligns with system requirements. Ensure proper ESD handling protocols are followed during installation due to CMOS sensitivity.

Selection Notes

Select this component when TTL-level compatibility is required alongside noise immunity provided by Schmitt triggers. Verify that the WQFN-14 footprint fits the PCB layout constraints. Ensure the design accounts for the recommended bypass capacitor placement near the VCC pin to maintain signal integrity.

Part Context

This device belongs to the SN74AHCT132 family of quadruple NAND gates. It shares identical pinouts with the SN74AHCT00 series, facilitating direct replacement in existing designs requiring Schmitt-trigger functionality. The AHCT series bridges standard CMOS logic with TTL input voltage specifications.
