SN74AC14WBQARQ1

Overview

The SN74AC14WBQARQ1 is an automotive-grade hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports input voltages up to 6 V. The device contains six independent inverters performing the Boolean function Y = NOT A. It features push-pull outputs with continuous drive capabilities of ±24 mA at 4.5 V and 5.5 V. Operating temperatures span from -40 °C to +125 °C. The component utilizes a WQFN-14 (BQA) package measuring 3.00 mm × 2.50 mm.

Feature Summary

Procurement Notes

Verify that the specific part number suffix matches the required package type, as variants exist for different form factors. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the ordering quantity aligns with the standard tape and reel packaging size defined in the manufacturer's documentation. Cross-reference the moisture sensitivity level rating with assembly timeline constraints.

Selection Notes

Select this component when designing circuits requiring robust signal inversion under noisy conditions or slow input transition rates. The wide voltage tolerance makes it suitable for systems interfacing between varying logic levels. Verify that the thermal resistance characteristics of the WQFN package meet the system's heat dissipation needs. Ensure unused inputs are properly biased to prevent undefined operational states.
