Overview
The SN74AHCT32QWBQARQ1 is an automotive-grade quadruple 2-input positive-OR gate from the AHCT series. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device features TTL-compatible inputs, ±8mA output drive capability at 5V, and low power consumption with a maximum ICC of 10µA. It is housed in a wettable flank WQFN-14 package.
Feature Summary
- AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classifications
- TTL-voltage compatible inputs enabling translation between communication modules and system controllers
- Low power consumption characteristics with minimal static supply current
- Wettable flank QFN package design facilitating enhanced inspection reliability
Applications
- Enable or disable digital signals
- Controlling indicator LEDs
- Translation between communication modules and system controllers
Procurement Notes
Verify the specific ordering suffix matches the required package type and reel quantity. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the component version aligns with the intended automotive qualification standards before finalizing procurement orders.
Selection Notes
Select this component when a quadruple OR gate function is required in automotive environments. The AHCT series ensures compatibility with TTL logic levels while operating at standard 5V supplies. Consider the WQFN package for space-constrained designs requiring robust solder joint visibility.
Part Context
This part belongs to the SN74AHCT32-Q1 family of automotive logic gates. It provides four independent 2-input OR gates within a single integrated circuit. The device is designed for high-reliability applications where signal combining and logic control are essential functions in vehicle electronics systems.
Replacement Considerations
Direct replacements include other SN74AHCT32-Q1 variants in different packages such as SOIC (D) or TSSOP (PW). Verify pinout compatibility and electrical specifications match before substitution.
