SN74LV4T32BQAR

Inverter Gates Overview

The SN74LV4T32BQAR is a quadruple 2-input positive-OR 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 voltage CMOS levels (e.g., 1.2 V to 1.8 V) and down-translation from higher voltage sources (e.g., 5.0 V to 3.3 V). It provides balanced CMOS outputs referenced to VCC and includes wettable flanks in the WQFN package for improved solder joint inspection.

Inverter Gates Feature Summary

• Integrated voltage level translation supporting both up-translation and down-translation between various CMOS logic families
• Schmitt-trigger inputs designed to accept slow or noisy signals without oscillation
• Balanced CMOS 3-state outputs capable of sourcing and sinking similar currents
• Wettable flank design on the WQFN package to facilitate automatic optical inspection

Inverter Gates Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals within mixed-voltage systems
• Controlling indicator LEDs across different voltage domains

Inverter Gates Procurement Notes

Verify that the specific BQA suffix corresponds to the WQFN-14 package with wettable flanks as documented in the manufacturer's datasheet. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the ordering information matches the exact revision history and package dimensions specified in the official product folder to avoid mechanical incompatibility during assembly.

Inverter Gates Selection Notes

Select this component when interfacing logic circuits operating at different voltage levels, such as translating between 1.8-V and 3.3-V domains. The integrated Schmitt triggers make it suitable for applications involving slow signal transitions or high-noise environments. Consider the thermal resistance characteristics of the WQFN package if high power dissipation is expected in dense layouts.

Inverter Gates Part Context

This part belongs to the SN74LV4T series of low-voltage CMOS logic devices featuring integrated level shifting. It is functionally related to other members of the LVxT family, which share similar input threshold enhancements and output drive capabilities. The BQA suffix specifically denotes the 14-pin WQFN package variant, distinguishing it from TSSOP or other package options available within the same logical family.

Inverter Gates Replacement Considerations

Direct substitutes include other SN74LV4T32 variants with different packaging, such as SN74LV4T32PW (TSSOP), provided the board layout accommodates the pinout differences. Cross-family replacements like SN74LVC1G32 may offer similar logic functions but lack the integrated voltage translation features.
