TXS0104EGXUR

Overview

The TXS0104EGXUR is a 4-bit bidirectional voltage-level translator from Texas Instruments, housed in a 12-pin GXU (MicroStar Junior) package. It utilizes two independent configurable power-supply rails: VCCA supports 1.65 V to 3.6 V, and VCCB supports 2.3 V to 5.5 V, with the constraint that VCCA must be less than or equal to VCCB. The device achieves maximum data rates of 24 Mbps for push-pull driving and 2 Mbps for open-drain driving. It operates within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Directionless translation architecture eliminates the need for external direction-control signals.
• Integrated internal pullup resistors facilitate direct connection to open-drain drivers without external components.
• Supports flexible power sequencing, allowing VCCA or VCCB to ramp up first without risk of damage.
• High electrostatic discharge protection ratings ensure robustness against human-body and charged-device model events.

Applications

• Handset devices
• Smartphones
• Tablets
• Desktop PCs

Procurement Notes

Verify the specific GXU package designation and suffix against the manufacturer's current orderable addendum to confirm physical dimensions and pinout compatibility. Ensure design requirements align with the recommended operating conditions regarding supply voltage limits and thermal performance metrics for this specific package type.

Selection Notes

Select this component when interfacing systems requiring bidirectional logic level translation between low-voltage nodes (1.65 V–3.6 V) and higher-voltage nodes (2.3 V–5.5 V). It is particularly suitable for applications utilizing open-drain interfaces due to integrated pullups. Consider the MicroStar Junior package constraints for high-density board layouts where space is limited.

Part Context

This part belongs to the TXS0104E family of 4-bit bidirectional voltage-level translators. The family shares identical electrical characteristics and functional descriptions but differs in packaging options such as SOIC, TSSOP, VQFN, and BGA. The GXU suffix specifically denotes the 12-pin MicroStar Junior package variant.

Replacement Considerations

Other packages within the same TXS0104E family, such as DSBGA (YZT), BGA (GXU/ZXU variants), SOIC (D), TSSOP (PW), and VQFN (RGY), are electrically equivalent. Verify pinout compatibility and thermal requirements when substituting with these alternative package types.
