Overview
The SN74AHC132BQAR is a quadruple positive-NAND gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature from -40°C to +125°C. The device features low drive capability, resulting in slow rise and fall times that minimize output signal ringing. It includes Schmitt-trigger inputs for added noise immunity and support of slow input transitions. The component utilizes a WQFN-14 package (BQA) measuring 3mm x 2.5mm.
Feature Summary
- Schmitt-trigger inputs provide enhanced noise immunity and support for slow input signal transitions.
- Low drive capability reduces output ringing through slow rise and fall times.
- Temperature-compensated threshold levels ensure stable operation across the specified temperature range.
- Inputs accept voltages up to 5.5V at any valid VCC, facilitating down voltage translation.
Applications
- Electronic points of sale
- Telecom infrastructure
- Network switches
- Tests and measurements
Procurement Notes
Verify the specific ordering suffix 'BQAR' corresponds to the WQFN-14 package and tape-and-reel quantity of 3000 units. Confirm RoHS compliance and lead finish details via the manufacturer's current Package Option Addendum. Ensure the procurement channel sources active production parts rather than obsolete variants like the PDIP or TSSOP versions.
Selection Notes
Select this component when bus interface applications require minimized overshoot and undershoot due to its low-drive characteristics. It is suitable for designs needing Schmitt-trigger action to handle noisy environments or slow-rising signals. Verify that the required logic function matches the quadruple 2-input NAND configuration and that the 2V to 5.5V supply range aligns with system power rails.
Part Context
This part belongs to the SN74AHC132 family of quadruple positive-NAND gates. It shares pinouts with other devices in the SNx4AHC series, such as the SN74AHC00, though logical functions differ. The BQA suffix specifically denotes the WQFN package variant designed for surface-mount assembly with a thermal pad.

FAQ
How does the Schmitt-trigger functionality benefit this NAND gate?
The Schmitt-trigger inputs provide different threshold levels for positive- and negative-going signals, allowing the device to trigger cleanly from slow input ramps while rejecting noise.
What is the primary advantage of the low-drive characteristic in this device?
The low drive results in slow rise and fall times, which minimizes ringing on the output signal, making it ideal for bus interface applications where signal integrity is critical.
