SN74AHCT00QPWRQ1

Overview

The SN74AHCT00QPWRQ1 is an automotive-grade quad 2-input NAND gate from the SN74AHCT00Q series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides a low-level output current of 8 mA and a high-level output current of -8 mA, with a propagation delay of 5.5 ns. It is housed in a TSSOP-14 package and supports surface-mount installation. The component is qualified to AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• TTL-compatible input logic levels enabling direct interfacing with legacy digital systems
• High noise immunity characteristics inherent to the AHCT logic family design

Applications

• Automotive electronic control units requiring robust logic gating
• Digital signal processing interfaces in vehicle networks
• General-purpose logic operations in automotive sensor modules

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and AEC-Q100 qualification. Ensure the 'PWR' designation matches the required TSSOP-14 package type for your PCB layout. Confirm that the 4.5 V to 5.5 V supply voltage requirement aligns with your system's power rails. Check datasheet revisions for any updates to thermal or electrical specifications before finalizing procurement.

Selection Notes

Select this component when automotive reliability and TTL compatibility are required. The AHCT series offers faster switching speeds compared to standard HCT devices while maintaining compatible input thresholds. Consider the TSSOP-14 package constraints regarding pin pitch and board space. Verify that the 5.5 ns propagation delay meets the timing requirements of your specific application circuit.

Part Context

This part belongs to Texas Instruments' SN74AHCT00Q family of single-function gates. It is specifically designed for automotive applications, distinguishing it from commercial variants through rigorous qualification processes. The device integrates four independent NAND gates into a single compact package, serving as a fundamental building block for complex digital logic circuits in vehicles.

Replacement Considerations
