SN74LV1T86QDCKRQ1

Inverter Gates Overview

The SN74LV1T86QDCKRQ1 is an automotive-grade, single-supply 2-input Exclusive-OR (XOR) gate and CMOS logic level shifter manufactured by Texas Instruments. It operates within a supply voltage range of 1.6 V to 5.5 V and supports data rates up to 150 Mbps at 5 V or 3.3 V supplies. The device features LVxT enhanced input voltage thresholds for effective up-translation from lower voltages (e.g., 1.2 V to 1.8 V) and down-translation from standard levels (e.g., 5.0 V to 3.3 V). It is housed in a DCK (SC-70-5) package with an operating temperature range of -40°C to +125°C.

Inverter Gates Feature Summary

• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classification levels.
• Integrated LVxT enhanced input voltage architecture enabling both up-translation and down-translation across various CMOS logic levels.
• Balanced CMOS push-pull outputs providing high drive capability while maintaining fast signal transition rates.

Inverter Gates Applications

• Detecting phase differences between input signals using low-pass filtering on the XOR output.
• Creating selectable inverters or buffers through specific input configurations.
• Translating voltage levels between disparate digital systems operating at different supply voltages.

Inverter Gates Procurement Notes

Verify that the ordering suffix matches the required package type and tape/reel specifications. Confirm AEC-Q100 qualification requirements align with the target automotive application standards. Ensure input signal transition rates comply with recommended operating conditions to prevent excessive power consumption or oscillation during operation.

Inverter Gates Selection Notes

Select this component when a single-supply XOR function combined with bidirectional voltage translation is required in space-constrained designs. The SC-70-5 package offers a compact footprint suitable for dense PCB layouts. Consider the LVxT input threshold characteristics if interfacing with low-voltage sources such as 1.2 V or 1.5 V CMOS devices.

Inverter Gates Part Context

This part belongs to the SN74LV1Txx-Q1 family of automotive single-supply logic level shifters. It shares the LVxT technology platform found in other members like the SN74LV1T32QDCKRQ1 but implements exclusive-OR logic rather than OR gates. The Q1 suffix denotes automotive qualification, distinguishing it from commercial grade counterparts.

Inverter Gates FAQ

How does the device handle unused inputs?

Unused inputs must not be left floating. They should be terminated directly to VCC or ground, or connected via a pull-up/pull-down resistor (typically 10 kΩ) to ensure valid logic states and prevent oscillation.

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 meeting all datasheet specifications. Exceeding this limit may degrade performance.
