SN74ACT00TDRQ1

Overview

The SN74ACT00TDRQ1 is an automotive-grade quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It belongs to the SNx4ACT logic series, designed for high-speed digital applications requiring robust performance in demanding environments. 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. Packaged in a small-outline integrated-circuit (SOIC) or similar surface-mount format with 14 pins, it features low input current and balanced output drive capabilities. Key electrical characteristics include a propagation delay of approximately 9.5 ns at 5 V and output currents of ±24 mA, ensuring reliable signal integrity in automotive electronic control units and other safety-critical systems.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for long-term reliability and durability in vehicle environments.
• High-speed CMOS technology providing fast switching times and low power consumption compared to standard TTL equivalents.
• Wide operating temperature range supporting functionality in extreme thermal conditions typical of under-hood automotive applications.
• Quad 2-input NAND configuration offering multiple logic functions within a single compact package.

Applications

• Electronic Control Units (ECUs) in automotive powertrain and chassis systems
• Body electronics and lighting control modules
• Infotainment system interface logic
• Sensor signal conditioning and processing circuits

Procurement Notes

Verify that the part number suffix 'TDRQ1' correctly denotes the specific tape-and-reel packaging and automotive grade variant. Confirm RoHS compliance status and ensure the supplier provides traceability documentation required for automotive assembly lines. Check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing automotive digital logic circuits requiring high noise immunity and fast propagation delays. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage constraint. Consider the SOIC package dimensions for PCB layout constraints. Verify that the load capacitance requirements are met to maintain the specified propagation delay performance.

Part Context

This component is part of the SNx4ACT family, which bridges the performance gap between standard AC and ACT logic families. It offers improved speed and lower power dissipation while maintaining compatibility with existing TTL/CMOS interfaces. The 'Q1' suffix indicates its qualification for automotive applications, distinguishing it from commercial-grade counterparts like the SN74ACT00D.

Replacement Considerations

Direct substitutes include other automotive-qualified quad NAND gates such as the SN74ACT00DBVRQ1 or SN74ACT00PWPRQ1, provided they match the package type and electrical specifications. Cross-reference with SN54ACT00 variants for military/aerospace requirements if higher temperature ranges are needed.
