Texas Instruments TXS0102DCUR 2-Bit Voltage Level Translator VSSOP-8

The Texas Instruments TXS0102DCUR is a bidirectional 2-bit voltage level translator IC designed to enable digital communication between mixed-voltage systems. This non-inverting translator uses two separate configurable power-supply rails, which removes the need for a dedicated direction-control signal and simplifies circuit design.

Overview

The A ports support operating voltages from 1.65V to 3.6V, while the B ports support voltages from 2.3V to 5.5V. This allows translation between standard logic levels such as 1.8V, 2.5V, 3.3V and 5V, making the device suitable for applications where multiple voltage domains coexist.

Key Features

• Output-enable (OE) input: when low, all I/O ports enter a high-impedance state, reducing quiescent current consumption
• VCC isolation: if either power supply is at ground, both ports become high-impedance, which supports system safety during power-up and power-down sequences
• No specific power-supply sequencing required, as either VCCA or VCCB can be ramped first
• Data rates of up to 24Mbps for push-pull configurations and 2Mbps for open-drain applications

Applications

The translator is designed for demanding environments and includes robust latch-up performance exceeding 100mA per JESD 78, Class II. It operates across a wide industrial temperature range from -40°C to 85°C and is housed in a compact VSSOP-8 package, which suits space-constrained designs. The device is also manufactured without antimony or bromine (No Sb/Br).
