Overview
The SN74AHCT32BQAR is a quadruple 2-input positive-OR gate from the SNx4AHCT32 family, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. The device features TTL-compatible inputs with high-level input voltage (VIH) of 2 V and low-level input voltage (VIL) of 0.8 V. Output drive capabilities include ±8 mA for both high and low states. Propagation delay ranges from 1 ns to 9 ns depending on load capacitance and temperature. The component is housed in a 14-pin WQFN (BQA) package measuring 3.00 mm × 2.50 mm.
Feature Summary
- TTL-voltage compatible inputs allow signal up translation from 3.3 V to 5 V systems.
- Low-drive CMOS technology minimizes output ringing, overshoot, and undershoot on signals.
- High electrostatic discharge protection exceeds JESD 22 standards for Human-Body Model and Machine Model.
Applications
- Electronic points-of-sale
- Telecom infrastructure
- Network switches
- Test and measurement
Procurement Notes
Verify the specific BQA package variant against the latest TI Package Option Addendum to confirm active production status and lead finish specifications. Ensure design compatibility with the 14-pin WQFN footprint dimensions and thermal pad requirements. Confirm that the selected carrier type matches the required quantity per reel or tube specifications provided in the packaging data.
Selection Notes
Select this component when bus-interface applications require reduced output edge rates to prevent signal integrity issues like ringing. The AHCT series provides necessary TTL input thresholds for interfacing with legacy logic levels while operating at standard 5 V CMOS supply voltages. Consider the WQFN package for space-constrained designs requiring efficient thermal dissipation through the exposed pad.
Part Context
This part belongs to the SNx4AHCT32 family of quadruple 2-input positive-OR gates. The family includes variants such as SN54AHCT32 for military/aerospace environments and other package options like SOIC, TSSOP, and VQFN. The SN74AHCT32BQAR specifically utilizes the WQFN form factor optimized for surface-mount assembly.

FAQ
How does the low-drive characteristic benefit circuit design?
The low-drive capability results in slow rise and fall times, which reduces output ringing and minimizes overshoot and undershoot, making it suitable for bus-interface applications where signal integrity is critical.
What is the input voltage tolerance for this device?
The inputs are TTL-voltage compatible, allowing them to accept voltages down to 3.3 V and translate up to 5 V. They are also overvoltage tolerant, allowing inputs to reach up to 5.5 V at any valid VCC.
