SN74LV4T08BQAR

Inverter Gates Overview

The SN74LV4T08BQAR is a quadruple 2-input positive-AND gate with integrated voltage level translation, manufactured by Texas Instruments. It operates on a single power supply ranging from 1.6 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device supports up to 150 Mbps data rates at 3.3-V or 5-V supplies. It provides balanced CMOS three-state outputs and includes 5.5-V tolerant input pins. The component is housed in a 14-pin WQFN package (BQA) measuring 3.00 mm by 2.50 mm.

Inverter Gates Feature Summary

• Integrated voltage level translation supporting both up-translation from lower voltages and down-translation from higher voltages
• Schmitt-trigger inputs designed to filter noise and ensure clean signal transitions
• Balanced CMOS three-state outputs capable of sourcing and sinking similar currents
• 5.5-V tolerant input pins allowing direct interfacing with higher voltage systems

Inverter Gates Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals within a circuit
• Controlling indicator LEDs directly from logic outputs

Inverter Gates Procurement Notes

Verify the specific BQA ordering suffix corresponds to the WQFN-14 package configuration required for your PCB layout. Confirm that the design accounts for the thermal pad connection guidelines specified in the datasheet. Ensure input signals comply with transition rate limits to prevent oscillation. Validate that output loading does not exceed the recommended capacitive load specifications during operation.

Inverter Gates Selection Notes

Select this component when simultaneous AND logic functionality and bidirectional voltage translation are required in a compact form factor. It is suitable for designs needing to interface low-voltage logic with 5-V tolerant buses. Consider the WQFN package constraints regarding thermal dissipation and soldering requirements. Verify that the operating temperature range meets the environmental conditions of the target application.

Inverter Gates Part Context

This part belongs to the SN74LV4T08 family of logic devices featuring integrated level shifting. The LVxT series is engineered for mixed-voltage systems where components operate at different supply levels. The BQA suffix specifically denotes the 14-pin WQFN package variant, distinguishing it from other package options like TSSOP available within the same logical function family.

Inverter Gates Replacement Considerations

Direct replacements must maintain the quadruple 2-input AND function with integrated translation. Verify pinout compatibility with the 14-pin WQFN footprint. Check that alternative parts support the 1.6 V to 5.5 V supply range and offer comparable propagation delay characteristics.
