SN74LV4T32QPWRQ1

Inverter Gates Overview

The SN74LV4T32QPWRQ1 is an automotive-grade quadruple 2-input positive OR gate with integrated voltage level 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 bidirectional translation between standard CMOS levels, including up-translation from lower voltages like 1.2 V or 1.8 V to higher levels such as 3.3 V or 5.0 V, and down-translation from 5.0 V or 3.3 V to 1.8 V. It provides balanced CMOS outputs capable of driving loads up to 150 Mbps at 5-V or 3.3-V supplies.

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 handle slow edge transitions without oscillation
• AEC-Q100 qualified for automotive applications with extended temperature range operation
• Available in packages featuring wettable flanks to facilitate automatic optical inspection

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific package variant (PW TSSOP or BQA WQFN) required for your design, as only certain packages include wettable flanks. Confirm that the selected part number suffix matches the desired thermal and mechanical specifications. Ensure input pins are terminated properly to prevent floating states during operation.

Inverter Gates Selection Notes

Select this component when interfacing logic circuits operating at different voltage domains, specifically requiring translation between 1.2 V/1.8 V sources and 3.3 V/5.0 V destinations. It is suitable for designs needing Schmitt-trigger noise filtering on inputs. Verify that the output drive current requirements do not exceed the specified limits for the chosen supply voltage.

Inverter Gates Part Context

This device belongs to Texas Instruments' LVxT family of logic devices, which are characterized by enhanced input voltage thresholds for level shifting. Unlike standard logic gates, these components integrate translation capabilities directly into the gate structure, reducing the need for external dedicated translator ICs in mixed-voltage automotive architectures.

Inverter Gates Replacement Considerations

Direct replacements must maintain the LVxT translation functionality and AEC-Q100 qualification. Non-automotive equivalents lack the required reliability standards. Standard OR gates without translation features cannot substitute this part due to incompatible voltage thresholds.
