Overview
The SN74AC14QPWRQ1 is an automotive-grade hex inverter from Texas Instruments, part of the SN74AC14-Q1 series. It features Schmitt-trigger inputs for noise filtering and operates within a supply voltage range of 2 V to 6 V. The device provides push-pull outputs with balanced high and low drive currents of 24 mA each. Designed for harsh environments, it supports operating temperatures from -40°C to +125°C and holds AEC-Q100 qualification. Packaged in a 14-pin TSSOP, it ensures signal integrity in automotive applications requiring robust logic inversion.
Feature Summary
- Automotive grade qualification compliant with AEC-Q100 standards
- Schmitt-trigger inputs provide effective noise filtering
- Balanced push-pull output drivers deliver strong current capability
- Wide operating temperature range suitable for extreme conditions
Applications
- Automotive electronic control units
- Signal conditioning in noisy vehicle environments
- Clock signal generation and shaping
- Pulse width modulation circuits
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 requirements for your target automotive application. Cross-reference the datasheet revision to confirm electrical characteristics match your design constraints. Confirm RoHS compliance status if required by your manufacturing process.
Selection Notes
Select this component when automotive reliability and Schmitt-trigger noise immunity are required. The AC series offers higher speed than standard TTL equivalents while maintaining compatibility. Verify that the 2 V to 6 V supply range aligns with your system power architecture. Consider the TSSOP package dimensions for PCB layout constraints.
Part Context
This device belongs to the SN74AC14-Q1 family of automotive inverters. It shares functional similarities with other AC-series logic but is specifically qualified for automotive use. The hex configuration allows multiple inversion functions in a single package, reducing board space compared to individual gates.
Replacement Considerations
Check for direct pin-compatible alternatives within the same automotive-qualified family. Verify that any substitute maintains the same Schmitt-trigger input characteristics and output drive strength. Ensure the replacement also holds AEC-Q100 certification if used in regulated automotive systems.
