SN74LV4T00BQAR

Inverter Gates Overview

The SN74LV4T00BQAR is a quadruple 2-input positive-NAND gate with integrated voltage translation, manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.6 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device supports up-translation from lower voltages (e.g., 1.2 V to 1.8 V) and down-translation using 5.5-V tolerant input pins. It provides balanced CMOS outputs capable of driving standard loads and achieves data rates up to 150 Mbps at 3.3 V or 5 V. The component is housed in a 14-pin WQFN package.

Inverter Gates Feature Summary

• Integrated voltage level translation supporting both up-conversion and down-conversion between various CMOS logic families

Inverter Gates Procurement Notes

Verify the specific BQA suffix indicates the WQFN package configuration during procurement. Confirm that the ordering part number matches the required pinout and thermal pad specifications. Ensure compatibility with the intended operating temperature range of -40°C to 125°C. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing design integration.

Inverter Gates Selection Notes

Select this component when designing systems requiring bidirectional voltage translation between disparate logic levels. It is suitable for applications needing Schmitt-trigger inputs to mitigate signal integrity issues caused by slow rise/fall times. Consider the WQFN package constraints regarding thermal dissipation and PCB layout requirements. Evaluate the maximum output current capabilities against the load requirements to ensure reliable operation across the full voltage range.
