TXB0104DG4

Translators, Level Shifters Overview

The TXB0104DG4 is a 4-bit bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes two separate configurable power-supply rails to facilitate universal low-voltage translation between various logic nodes. The A port accepts supply voltages from 1.2 V to 3.6 V, while the B port accepts voltages from 1.65 V to 5.5 V, with the constraint that VCCA must not exceed VCCB. This device supports data rates up to 100 Mb/s and features a propagation delay of 7.4 ns. It operates within an extended temperature range of -40°C to +85°C and is housed in a 14-pin SOIC package.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage translation between multiple low-voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V.
• Features Ioff circuitry to disable outputs and prevent damaging current backflow when the device is powered down.
• Includes VCC isolation functionality where all outputs enter a high-impedance state if either VCC input is at ground potential.

Translators, Level Shifters Applications

• Smartphones
• Tablets
• Desktop computers

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DG4' corresponds to the RoHS-compliant version in the official Texas Instruments datasheet. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the design accommodates the requirement that VCCA does not exceed VCCB for proper operation across the specified voltage ranges.

Translators, Level Shifters Selection Notes

Select this component when interfacing between mixed-voltage domains requiring high-speed bidirectional data transfer up to 100 Mb/s. It is suitable for applications needing automatic direction sensing without external control signals. Consider the 1.2V minimum operating voltage for A-port compatibility with modern low-power logic families.

Translators, Level Shifters Part Context

This part belongs to the TXB0104 family of voltage-level translators. It serves as a non-inverting buffer designed to bridge different voltage standards in digital systems. The DG4 suffix indicates a specific manufacturing variant compliant with environmental directives, distinct from other packaging options like TSSOP or QFN found in the broader product line.

Translators, Level Shifters Replacement Considerations

The TXB0104D is a direct functional equivalent within the same series. Verify package compatibility when substituting, as the DG4 specifies the SOIC-14 form factor. Other family members may offer different pin counts or speed characteristics.
