TXB0104PWR

The TXB0104PWR is a 4-bit non-inverting translator IC uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB. VCCB 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, 3.3V 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. 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. It is designed so that the OE input circuit is supplied by VCCA.

• 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 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, No Sb/Br

Applications
