TXB0108NMER

Translators, Level Shifters Overview

The TXB0108NMER is an 8-bit bidirectional voltage-level translator manufactured by Texas Instruments, housed in a 20-ball NFBGA package. It supports VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V. The device features auto-direction sensing, achieving data rates up to 100 Mbps with propagation delays as low as 4 ns. It includes ±15kV HBM ESD protection on the B port and offers low power consumption with a maximum ICC of 4μA.

Translators, Level Shifters Feature Summary

• Auto-direction sensing enables universal bidirectional translation between different voltage nodes without requiring explicit direction control signals.
• VCC isolation feature places all outputs in a high-impedance state if either supply input is at ground potential.
• Supports partial-power-down mode operation via Ioff circuitry to prevent damaging current backflow during power-down sequences.

Translators, Level Shifters Applications

• Handset
• Smartphone
• Tablet
• Desktop PC

Translators, Level Shifters Procurement Notes

Verify the specific NME suffix corresponds to the required nFBGA-20 package dimensions and pinout configuration for your PCB layout. Confirm that the operating temperature range meets your environmental requirements. Ensure proper handling procedures are followed due to the sensitivity of the MOS gates to electrostatic discharge during storage and assembly.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic between systems operating at distinct voltage levels within the specified ranges. Ensure VCCA does not exceed VCCB during operation. Consider the thermal resistance characteristics of the NFBGA package for heat dissipation needs. Verify compatibility with push-pull CMOS logic outputs, as open-drain signals require alternative solutions.

Translators, Level Shifters Part Context

This part belongs to the TXB0108 family of 8-bit bidirectional translators. It shares core functional specifications with other package variants such as TXB0108YZPR and TXB0108PWR. The primary distinction lies in the physical packaging and associated thermal properties, while maintaining identical electrical performance and pin functionality across the series.

Translators, Level Shifters Replacement Considerations

Direct substitutes include other packages within the same TXB0108 family, such as TXB0108YZPR or TXB0108PWR, provided the mechanical footprint and thermal management strategies are compatible with the design constraints.
