TXB0104PWR

Overview

The TXB0104PWR is a 4-bit bidirectional voltage-level translator in a TSSOP-14 package. It utilizes two independent configurable power rails: VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V), with VCCA not exceeding VCCB. The device supports data rates up to 100 Mb/s and features a propagation delay of 7.4 ns. Operating temperatures range from -40°C to +85°C, with a maximum supply voltage of 5.5V.

Feature Summary

• Supports universal low-voltage bidirectional translation between multiple voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V.
• Includes Ioff circuitry to disable outputs during power-down, preventing damaging current backflow for partial power-down applications.
• Features VCC isolation where all outputs enter a high-impedance state if either VCC input is at ground potential.

Applications

• Audio equipment
• Consumer electronics
• Computer systems and peripherals

Procurement Notes

Verify the specific suffix 'G4' against the ordered part number, as it indicates RoHS compliance and green material status. Confirm the TSSOP-14 package type matches the design requirements. Ensure the application voltage constraints are strictly observed, specifically that VCCA must not exceed VCCB. Validate that the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this component when interfacing logic circuits between different low-voltage domains requiring bidirectional data transfer. It is suitable for designs needing auto direction sensing without external control signals. Consider the TSSOP-14 footprint availability and the specific voltage rail configurations required by the source and destination devices.

Part Context

This device belongs to the Texas Instruments TXB0104 series of voltage level translators. It is designed for general-purpose bidirectional translation in mixed-voltage systems. The family offers various package options, with the PWR variant providing surface-mount convenience in a thin-shrink small-outline package.

Replacement Considerations

TXB0104PWRE4 is an equivalent RoHS-compliant alternative within the same product line.
