Overview
The SN74AHCT00QDRQ1 is an automotive-grade quad two-input NAND gate manufactured by Texas Instruments. It belongs to the SN74AHCT-Q1 series, designed for high-speed digital applications requiring CMOS compatibility with TTL voltage levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. It features low dynamic power consumption and offers 8 mA output drive capability in both high and low states. The component is qualified under AEC-Q100 standards and is available in a 14-pin SOIC surface-mount package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
- CMOS technology ensuring low static power consumption while maintaining high noise immunity
- TTL-compatible input thresholds allowing direct interfacing with TTL logic systems
- Wide operating temperature range supporting harsh automotive thermal conditions
Applications
- Automotive electronic control units (ECUs)
- Infotainment system logic processing
- Body control module signal gating
- Instrument cluster interface circuits
Procurement Notes
Verify the complete part number including the suffix 'QDRQ1' to ensure correct automotive grade, package type, and tape-and-reel packaging configuration. Confirm that the design-in process accounts for the specific 14-pin SOIC footprint and pinout requirements. Ensure compliance with AEC-Q100 reliability targets for the intended automotive application zone. Check for any recent product change notifications regarding manufacturing site or material composition updates.
Selection Notes
Select this component when a quad NAND gate is required in automotive designs needing 5V TTL compatibility. The AHCT series provides faster switching speeds compared to standard 74HC devices while maintaining lower power dissipation than older bipolar technologies. Consider the 14-pin SOIC package constraints for PCB layout density. Verify that the 4.5V to 5.5V supply voltage aligns with the system's power rail specifications.
Part Context
This part is part of Texas Instruments' SN74AHCT-Q1 family of automotive-qualified logic ICs. The family includes various logic functions such as inverters, buffers, and flip-flops, all sharing similar electrical characteristics and automotive reliability standards. The 'AHCT' designation indicates advanced high-speed CMOS technology with TTL-compatible inputs, distinguishing it from the standard AHC series which has CMOS-compatible inputs.
Replacement Considerations
SN74AHCT00QPWRQ1: Same logical function and electrical specifications but housed in a TSSOP-14 package instead of SOIC-14. Requires PCB footprint modification.
