Overview
The SN74AHC32QPWRG4Q1 is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the AHC logic family and features CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation in a TSSOP-14 package. It provides low-level output current of 8 mA and high-level output current of -8 mA, with a propagation delay of 5.1 ns. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- TTL-compatible input thresholds for direct interfacing
- Wide operational supply voltage range supporting 2 V to 5.5 V
- High-speed performance with low propagation delay
Applications
- Automotive electronic control units
- Signal routing in vehicle networks
- Logic level translation in mixed-voltage systems
- Data bus arbitration circuits
Procurement Notes
Verify the complete part number including suffixes such as G4 and Q1 to ensure correct packaging and automotive qualification status. Confirm that the specific revision matches project requirements for temperature range and electrical characteristics. Cross-reference manufacturer documentation for any updates regarding pin configuration or recommended soldering profiles prior to integration.
Selection Notes
Select this component when automotive reliability is required alongside fast switching speeds. The AHC series offers improved speed over standard HC devices while maintaining compatibility. Ensure the design accommodates the specified output drive capabilities and thermal constraints associated with the TSSOP-14 package in enclosed automotive environments.
Part Context
This part is a member of the SN74AHC32Q family, which includes various logic functions tailored for automotive use. It shares the same package and basic electrical characteristics with other members like SN74AHCT32QPWRG4Q1 but differs in logic function and input threshold specifications. The Q1 suffix denotes automotive grade qualification.
Replacement Considerations
SN74AHCT32QPWRG4Q1 offers similar form factor but different input thresholds. SN74AHC32QPWRQ1 is the non-G4 variant with identical functionality. Verify pinout compatibility and electrical parameters before substitution.
