TXS0104VQBQARQ1

Translators, Level Shifters Overview

The TXS0104VQBQARQ1 is a 4-bit bidirectional voltage translator designed for open-drain and push-pull applications. It features two configurable power-supply rails: VCCA (1.65V to 3.6V) and VCCB (2.3V to 5.5V), with VCCA required to be less than or equal to VCCB during operation. The device supports maximum data rates of 24Mbps for push-pull driving and 2Mbps for open-drain driving. It includes integrated 10kΩ pullup resistors on each I/O line, eliminating the need for external components in many open-drain configurations. The OE input controls the high-impedance state.

Translators, Level Shifters Feature Summary

• Directionless translation architecture eliminates the need for a direction-control signal
• Integrated 10kΩ pullup resistors on all I/O lines simplify open-drain circuit design
• No power-supply sequencing requirements allow either rail to ramp first without damage
• High ESD protection ratings exceed standard automotive and industrial requirements

Translators, Level Shifters Applications

• Smartphone systems
• Tablet devices
• Handset electronics
• Desktop PC interfaces

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix QBA corresponds to the WQFN package type and RQ1 indicates AEC-Q100 qualification status. Confirm the specific pin configuration matches the BQA package diagram provided in the datasheet. Ensure supply chain documentation aligns with Texas Instruments' production data standards for automotive-grade components.

Translators, Level Shifters Selection Notes

Select this component when interfacing between low-voltage logic domains (1.8V, 2.5V, 3.3V) and higher voltage domains (3.3V, 5V). It is particularly suitable for open-drain buses where internal pullups are desired. Consider the WQFN package dimensions if board space is constrained. Verify that the operating temperature range meets system requirements.

Translators, Level Shifters Part Context

This part belongs to the TXS0104V family of bi-directional level shifters. The base model offers four channels of voltage translation. The specific suffixes denote the package style (WQFN) and automotive qualification grade. It serves as a bridge between different voltage domains in mixed-signal systems.

Translators, Level Shifters Replacement Considerations

The TXB0104 is an alternative for push-pull applications but lacks the integrated pullups. Other members of the TXS010x family offer different channel counts. Verify pin compatibility before substitution.

Translators, Level Shifters FAQ

Does the device require a direction control signal?

No, the TXS0104V uses a directionless architecture that automatically determines the data flow direction.

What is the function of the OE pin?

The OE (Output Enable) pin places all outputs in a high-impedance state when driven low.

Are external pullup resistors necessary?

No, the device integrates 10kΩ pullup resistors on each I/O line, which is sufficient for many open-drain applications.
