Overview
The SN74AHC32QPWRQ1 is an automotive-grade quad 2-input positive-OR gate from Texas Instruments, qualified to AEC-Q100 standards. It operates within a voltage range of 2 V to 5.5 V and features a TSSOP-14 package. Key electrical parameters include a propagation delay of 7.5 ns at 5 V with a 50 pF load, low static current of 2 µA, and output drive capabilities of ±8 mA. The device supports an operating temperature range from -40°C to +125°C, ensuring reliability in demanding automotive environments.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for robust performance
- Wide supply voltage operation ranging from 2 V to 5.5 V
- Low power consumption with minimal static current draw
- High-speed logic performance suitable for critical timing applications
Applications
- Automotive electronic control units (ECUs)
- Infotainment system logic interfaces
- Body control module signal processing
- Sensor interface circuits in vehicle networks
Procurement Notes
Verify the specific suffix 'PWRQ1' corresponds to the TSSOP-14 package and tape-and-reel orientation required for your assembly line. Confirm that the AEC-Q100 grade matches your vehicle's thermal and reliability specifications. Ensure compatibility with your PCB footprint design for the 14-pin thin-shrink small-outline package before finalizing orders.
Selection Notes
Select this component when automotive reliability is mandatory alongside low-voltage operation down to 2 V. It serves as a direct replacement for non-automotive SN74AHC32 variants where environmental resilience is required. Consider the TSSOP-14 form factor for space-constrained designs requiring surface-mount integration without sacrificing drive strength or speed.
Part Context
This part belongs to the SN74AHC32-Q1 family of single-function gates designed specifically for automotive electronics. It shares logical functionality with standard industrial logic but includes enhanced testing and documentation to meet automotive quality requirements. The Q1 suffix denotes its qualification for use in vehicles, distinguishing it from commercial-grade counterparts.
Replacement Considerations
SN74AHC32PW is the commercial equivalent without automotive qualification. SN74HCS32QPWRQ1 offers higher drive current but different input characteristics. Verify pinout compatibility and voltage thresholds when substituting.
