Overview
The SN74AHCT14QWBQARQ1 is an automotive-grade hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +125°C. The device features TTL-compatible inputs, ±8 mA output drive capability, and latch-up performance exceeding 250 mA per JESD 17. It utilizes the EPIC process and is housed in a 14-pin WQFN package.
Feature Summary
- Qualified for automotive applications with AEC-Q100 certification
- TTL-voltage compatible inputs support slow and noisy signals
- Schmitt-trigger action provides distinct input thresholds for noise immunity
Applications
- Synchronize inverted clock inputs
- Debounce a switch
- Invert a digital signal
Procurement Notes
Verify the specific ordering suffix matches the required package type and reel quantity. Confirm RoHS compliance and lead finish details against the latest Package Information Addendum. Ensure the component status is listed as Active Production before finalizing procurement plans.
Selection Notes
Select this component when TTL-level compatibility is required at 5V logic levels. The Schmitt-trigger inputs are essential for cleaning up noisy or slowly rising signals. Verify that the WQFN-14 package fits the available PCB footprint and thermal requirements.
Part Context
This part belongs to the SN74AHCT14Q-Q1 family of automotive inverters. It shares functional characteristics with other members of the series but differs in physical packaging. The WBQA suffix specifically denotes the 14-pin WQFN (BQA) package variant.
Replacement Considerations
SN74AHCT14QDRQ1 (SOIC-14), SN74AHCT14QPWRQ1 (TSSOP-14). These parts share identical electrical specifications and functionality but utilize different surface-mount packages.
