Overview
The SN74AHC08QPWRDL is a quadruple 2-input positive-AND gate from Texas Instruments' AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and features a propagation delay of 9 ns. The device supports low-level output currents of 8 mA and high-level output currents of -8 mA. It is qualified under the AEC-Q100 standard for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- Wide operational voltage range supporting 2 V to 5.5 V supplies
- High-speed performance with 9 ns propagation delay
- Robust output drive capability at 8 mA
Applications
- Automotive electronic control units
- Digital signal processing interfaces
- Portable battery-powered equipment
Procurement Notes
Verify the complete part number including suffixes such as 'Q1' or 'G4' to ensure correct automotive qualification and tape-and-reel packaging specifications. Confirm that the specific variant matches the required package type, typically TSSOP-14, and validate the temperature grade against application constraints. Cross-reference official manufacturer documentation to confirm RoHS compliance status before procurement.
Selection Notes
Select this component when automotive reliability and wide voltage operation are required. The AHC series offers speed comparable to ALVC while maintaining CMOS power efficiency. Ensure input pins are tied to VCC or GND if unused to prevent undefined states. Verify that the 14-TSSOP package dimensions fit the PCB layout constraints and thermal requirements of the target design.
Part Context
This part belongs to the SN74AHC08Q series, which denotes automotive-grade quadruple 2-input AND gates. It is part of the broader 74AHC logic family, designed for high-speed digital applications requiring low power consumption. The 'Q' suffix indicates qualification for automotive environments, distinguishing it from standard commercial variants.
Replacement Considerations
Compatible substitutes include other AEC-Q100 qualified quad 2-input AND gates from the same family, such as the SN74AHC08QPWRE4 or SN74AHC08QPWRG4Q1. Ensure pin compatibility and identical electrical characteristics before substitution.
