Overview
The SN74AC08QDRQ1 is a quad two-input positive AND gate manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2 V to 6 V and supports an extended operating temperature range from -40°C to +125°C. The device features a maximum propagation delay of 7.5 ns at 5 V and provides symmetric output drive currents of 24 mA for both high and low states. Packaged in a 14-pin SOIC surface-mount format, it holds AEC-Q100 qualification.
Feature Summary
- Automotive-grade reliability with AEC-Q100 certification
- High-speed logic performance with 7.5 ns propagation delay
- Wide power supply operation from 2 V to 6 V
- Strong push-pull output capability with 24 mA drive current
Applications
- Digital logic circuits in automotive systems
- LED driving interfaces
- Digital signal processing units
- Control and automation modules
Procurement Notes
Verify the specific suffix G4 indicates a lead-free variant compliant with RoHS standards. Confirm the package type matches the required SOIC-14 footprint. Ensure the component meets the necessary AEC-Q100 grade requirements for the target automotive application environment.
Selection Notes
Select this component when automotive qualification is mandatory alongside high-speed switching capabilities. The AC series offers faster performance than standard HC or HCS variants while maintaining compatibility with 2 V to 6 V logic levels. Verify that the 24 mA output current suffices for the intended load without external buffering.
Part Context
This part belongs to the SN74AC08-Q1 family of automotive quad two-input positive AND gates. It shares functional similarities with the SN74HC08QDRQ1 but provides significantly higher output drive current and faster switching speeds. The device serves as a robust solution for complex digital logic implementations in demanding automotive environments.
Replacement Considerations
SN74AC08QDRG4Q1 is a confirmed substitute offering identical electrical characteristics and packaging.
