TXS0104EBQAR

Overview

The TXS0104EBQAR is a four-bit bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes two separate configurable power-supply rails, with the A port tracking VCCA (1.65 V to 3.6 V) and the B port tracking VCCB (2.3 V to 5.5 V). The device supports maximum data rates of 24 Mbps in push-pull configurations and 2 Mbps in open-drain applications. It operates within an ambient temperature range of -40°C to +85°C and features a WQFN-14 package.

Feature Summary

• Bidirectional translation between low-voltage nodes without requiring external direction-control signals
• Independent power supply rails allow flexible voltage node translation from 1.65 V to 5.5 V
• High electrostatic discharge protection exceeding JESD 22 standards for both ports
• Output-enable pin allows all outputs to be placed in a high-impedance state

Applications

• Smartphones
• Tablets
• Handheld devices
• Desktop computers

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm the automotive or industrial grade requirements align with the component's rated operating temperature range. Ensure the design accounts for the OE pin pull-down resistor value based on driver current-sourcing capabilities during power-up sequences.

Selection Notes

Select this component when interfacing logic families with different supply voltages, specifically where VCCA must remain lower than or equal to VCCB. Consider the WQFN-14 package for space-constrained designs. Evaluate the open-drain versus push-pull output configuration needs against the target data rate requirements before finalizing the selection.

Part Context

This part belongs to the TXS0104E family of voltage translators designed for CMOS logic applications. The 'BQA' suffix indicates the specific WQFN-14 packaging variant. The series is engineered for low-power consumption and robust ESD performance, making it suitable for portable consumer electronics and general-purpose digital interfaces.

FAQ

Does the TXS0104EBQAR require a direction control signal?

No, the device does not need a direction-control signal as it automatically senses the direction of data flow.

What is the relationship between VCCA and VCCB?

VCCA must be less than or equal to VCCB, allowing the A port to track voltages from 1.65 V to 3.6 V while the B port tracks 2.3 V to 5.5 V.
