Overview
The SN74AHC32QWBQARQ1 is an automotive-qualified quadruple 2-input positive-OR gate from Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±8mA drive at 5V, with a maximum ICC of 10µA. It utilizes a WQFN-14 package (BQA) measuring 3mm x 2.5mm. ESD protection meets AEC Q100 standards with HBM Level 2 (±2000V) and CDM Level C4B (±1000V).
Feature Summary
- Qualified for automotive applications with extended temperature operation.
- Standard CMOS inputs require termination to prevent floating states.
- Balanced CMOS push-pull outputs provide symmetric current sourcing and sinking.
- Includes internal clamp diodes on inputs and outputs for transient protection.
Applications
- Enable or disable digital signals in control circuits.
- Controlling indicator LEDs based on logic conditions.
- Signal translation between communication modules and system controllers.
Procurement Notes
Verify the specific ordering suffix matches the required package type, as the SN74AHC32Q-Q1 family includes SOIC, TSSOP, and WQFN options. Confirm that the BQA package designation aligns with the PCB footprint requirements. Ensure the component meets the necessary AEC-Q100 reliability standards for the intended automotive environment before finalizing procurement specifications.
Selection Notes
Select this component when four independent OR gates are required in a compact surface-mount form factor. It is suitable for designs needing wide supply voltage compatibility from 2V to 5.5V. Consider its low power consumption and high noise immunity for systems where signal integrity and energy efficiency are critical constraints.
Part Context
This part belongs to the SN74AHC32Q-Q1 series, which consists of quadruple 2-input positive-OR gates designed for automotive use. The 'WBQA' suffix specifically denotes the WQFN-14 package variant. It is part of Texas Instruments' broader portfolio of high-speed CMOS logic devices optimized for demanding electronic environments.
Replacement Considerations
Direct replacements include other SN74AHC32Q-Q1 variants with different packages, such as SN74AHC32QDRQ1 (SOIC) or SN74AHC32QPWRQ1 (TSSOP), provided the board layout accommodates the pinout differences. Verify electrical characteristics match if substituting with non-TI equivalents.
