TXS0101QDCKRQ1

Translators, Level Shifters Overview

The TXS0101QDCKRQ1 is an automotive-grade, 1-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It features auto-direction sensing without requiring a direction-control signal. The device supports VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V. Maximum data rates are 50Mbps for push-pull and 2Mbps for open-drain configurations. It operates within an ambient temperature range of -40°C to +125°C and includes integrated 10kΩ pullup resistors.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DCKRQ1 corresponds to the SC-70-6 package and tape-and-reel quantity requirements. Confirm that the AEC-Q100 qualification grade matches the thermal and reliability specifications required for the target automotive application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with mismatched logic voltages such as 1.8V to 3.3V or 5V. Ensure the driving source impedance is below 50Ω to achieve specified data rates. Verify that the OE pin configuration aligns with system power-up sequencing needs.

Translators, Level Shifters Part Context

This part belongs to the Texas Instruments TXS0101-Q1 family of level-shifters. It is specifically engineered for automotive electronics requiring robust voltage translation between low-voltage controllers and higher-voltage peripherals.

Translators, Level Shifters Replacement Considerations

For non-automotive applications, the standard TXS0101 may be considered if AEC-Q100 qualification is not required.
