SN74LV4T08QWBQARQ1

Inverter Gates Overview

The SN74LV4T08QWBQARQ1 is an automotive-grade quadruple 2-input positive-AND gate with integrated voltage translation. 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 voltage CMOS inputs (e.g., 1.2 V to 1.8 V) and down-translation via 5.5-V tolerant input pins. It achieves transmission rates up to 150 Mbps at 3.3 V or 5 V VCC, meets AEC-Q100 Grade 1 standards (-40°C to +125°C), and utilizes a 14-pin WQFN package with wettable flanks.

Inverter Gates Feature Summary

• Integrated single-supply voltage translation supporting both up-conversion and down-conversion between various CMOS logic levels
• Automotive qualification compliant with AEC-Q100 Grade 1 specifications for high reliability in demanding environments
• Schmitt-trigger inputs provide enhanced noise filtering and signal integrity during transitions
• Wettable flank QFN packaging facilitates reliable soldering and enables effective automatic optical inspection

Inverter Gates Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals within control circuits
• Controlling indicator LEDs in automotive systems

Inverter Gates Procurement Notes

Verify the specific WBQA package suffix matches the required wettable flank configuration. Confirm that the component holds valid AEC-Q100 certification documentation for the target automotive application. Ensure the design accounts for the specified thermal resistance values and absolute maximum ratings to prevent damage during operation.

Inverter Gates Selection Notes

Select this component when a single power supply must interface different voltage domains without external level shifters. It is suitable for designs requiring robust noise immunity through Schmitt triggers. Verify that the load capacitance does not exceed 50 pF to maintain specified switching performance. Consider the thermal characteristics of the WQFN package for heat dissipation requirements.

Inverter Gates Part Context

This part belongs to Texas Instruments' LVxT family of logic devices designed for low-voltage applications. Unlike standard logic gates, the LVxT series incorporates specialized input structures to facilitate seamless voltage translation. The SN74LV4T08 variant specifically provides four independent AND functions, combining logical processing with signal conditioning capabilities.

Inverter Gates Replacement Considerations

The SN74LV4T08-Q1 serves as the base model for this component. Other packages such as TSSOP are available under the same electrical specifications but lack the wettable flank feature.
