TXB0104NMNR

Overview

The TXB0104NMNR 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 voltage nodes, including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V. The device supports data rates up to 100 Mb/s with propagation delays of 3.8 ns and 4 ns. It operates within a supply voltage range of 1.2 V to 5.5 V and functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a compact NFBGA-12 package designed for surface-mount technology applications.

Feature Summary

• Supports bidirectional voltage translation between A port (1.2V to 3.6V) and B port (1.65V to 5.5V) using independent power rails
• Includes Ioff circuitry to disable outputs and prevent damaging current backflow during partial power-down conditions
• Features VCC isolation functionality that places all outputs in a high-impedance state if either power input is at ground potential

Applications

• Mobile phones and smartphones
• Tablet computers
• Desktop computer systems
• Audio equipment such as headsets

Procurement Notes

Verify the specific package type matches the design requirements, as the NMNR suffix indicates an NFBGA-12 configuration distinct from other variants like TSSOP or SOIC. Confirm that the manufacturer source aligns with official Texas Instruments documentation to ensure authenticity. Check for RoHS compliance status and moisture sensitivity levels prior to integration into the manufacturing process.

Selection Notes

Select this component when designing circuits requiring low-power bidirectional translation between mixed voltage domains. Ensure the application does not exceed the maximum supply voltage limits or operate outside the specified temperature range. Consider the NFBGA-12 package constraints regarding PCB layout and thermal management compared to larger footprint alternatives.

Part Context

This part belongs to the TXB0104 series of logic ICs focused on voltage level translation. It serves as a critical interface component in mixed-signal systems where different voltage standards must communicate. The series is widely used in consumer electronics and computing peripherals to bridge gaps between low-voltage processors and higher-voltage peripheral interfaces.

Replacement Considerations
