TXB0104RUTR

The TXB0104RUTR is a 4-bit Bidirectional Voltage-level Shifter with auto direction sensing and ±15kV ESD protect. This non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA and accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB and accepts any supply voltage from 1.65 to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2, 1.5, 1.8, 2.5, 3.3 and 5V voltage nodes. VCCA should not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

• 1.2 to 3.6V on A port and 1.65 to 5.5V on B port (VCCA ≤ VCCB)
• VCC isolation feature - If either VCC input is at GND, all outputs are in the high-impedance state
• OE input circuit referenced to VCCA
• Low power consumption (5µA maximum ICC)
• IOFF supports partial power-down-mode operation
• Latch-up performance exceeds 100mA per JESD 78, class II
• Green product and no Sb/Br

Warnings

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
