SN74LV1T32QDBVRQ1

Inverter Gates Overview

The SN74LV1T32QDBVRQ1 is an automotive-grade, single-channel 2-input positive-OR gate featuring integrated voltage level translation. It operates on a single supply voltage ranging from 1.6V to 5.5V and supports CMOS logic levels of 1.8V, 2.5V, 3.3V, and 5V. The device provides balanced push-pull outputs with up to 15mA drive capability at higher voltages. Propagation delay ranges from approximately 3.9ns to 18.3ns depending on the supply voltage and load capacitance. It is qualified to AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Inverter Gates Feature Summary

• Integrated LVxT enhanced input voltage thresholds enable seamless up-translation from lower voltage CMOS inputs (e.g., 1.2V or 1.8V) to higher output levels without external components.
• 5.5V tolerant input pins allow direct down-translation of standard 5.0V, 3.3V, or 2.5V signals to lower voltage system controllers.
• Balanced CMOS push-pull outputs provide symmetric sourcing and sinking capabilities for fast signal transitions into light loads.

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DBVR suffix denotes the SOT-23-5 package. Confirm that the component meets the AEC-Q100 qualification requirements for your specific automotive application environment. Ensure the design accounts for the recommended operating conditions regarding supply voltage and input transition rates to prevent oscillation.

Inverter Gates Selection Notes

Select this component when a compact solution is needed for both logical OR operations and bidirectional voltage translation within a single package. It is suitable for designs requiring interface between disparate voltage domains, such as connecting 1.2V sensors to 3.3V microcontrollers. Consider the propagation delay specifications relative to your system's timing constraints at the target supply voltage.

Inverter Gates Part Context

This part belongs to Texas Instruments' SN74LVxT-Q1 family of automotive logic devices. These components are designed to bridge different voltage domains while performing basic logic functions. The Q1 suffix indicates automotive qualification, ensuring reliability under harsh environmental conditions typical in vehicle electronics compared to standard commercial grade parts.

Inverter Gates Replacement Considerations

SN74LVC1T32QDBVRQ1: Standard LVC series without integrated translation features; requires external level shifting if voltage domains differ.

Inverter Gates FAQ

How does the device handle unused inputs?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using a pull-up or pull-down resistor, typically 10kΩ, to ensure valid logic states and prevent excessive power consumption.

What is the maximum capacitive load supported?

The device can drive a load with a total capacitance less than or equal to 50 pF while still meeting all datasheet specifications. Exceeding this limit may degrade performance.
