SN74AHC32BQAR

Overview

The SN74AHC32BQAR is a commercial-grade quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and provides ±8mA output drive capability at 5V. The device features low power consumption with a maximum ICC of 10µA and latch-up performance exceeding 250mA per JESD 17. It utilizes standard CMOS inputs and balanced push-pull outputs, housed in a WQFN-14 package.

Feature Summary

• Quadruple 2-input positive-OR logic function
• Wide operating voltage range from 2V to 5.5V
• Balanced CMOS push-pull outputs for robust signal driving

Applications

• Enabling or disabling digital signals
• Controlling indicator LEDs
• Translation between communication modules and system controllers

Procurement Notes

Verify the specific BQA suffix corresponds to the WQFN-14 package configuration required for your PCB layout. Confirm that the commercial temperature rating (-40°C to +125°C) aligns with your operational environment. Ensure input pins are terminated properly to prevent floating states during operation.

Selection Notes

Select this component when a wide supply voltage range including 2V is required alongside standard OR logic functionality. It is suitable for applications needing moderate output drive current without the complexity of tri-state buffers. Verify thermal requirements against the junction-to-ambient resistance specifications for the WQFN-14 package.

Part Context

This part belongs to the SNx4AHC32 family of quadruple 2-input positive-OR gates. The 'SN' prefix indicates it is a commercial-grade device produced by Texas Instruments. The 'BQA' suffix specifically denotes the WQFN-14 surface-mount package variant, distinguishing it from other package options like SOIC or TSSOP within the same logical family.

Replacement Considerations

Direct replacements include other SN74AHC32 variants with different packages such as SN74AHC32DR (SOIC) or SN74AHC32DBR (SSOP), provided pin compatibility and thermal constraints are met.
