Overview
The SN74AHC00QWBQARQ1 is an automotive-grade quadruple 2-input positive-NAND gate from the SN74AHC00-Q1 series. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating free-air temperature range of -40°C to +125°C. The device features latch-up performance exceeding 250 mA per JESD 17-2. It utilizes a WQFN (BQA) package with 14 pins, measuring 3 mm by 2.5 mm. The component is qualified for automotive applications and includes electrostatic discharge protection ratings of ±2000 V via human body model and ±1000 V via charged device model.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- Wide operating supply voltage range from 2 V to 5.5 V
- High latch-up immunity exceeding specified current thresholds
- Robust electrostatic discharge protection capabilities
Applications
- Automotive electronic systems requiring logic gating
