TXS0108E - 8-Bit Bidirectional Voltage-Level Shifter For Open-Drain And Push-Pull Application

This 8-bit non-inverting translator uses two separate configurable power-supply rails.The A port tracks the V_CCA pin supply voltage. TheV_CCA pin accepts any supply voltage between 1.2V and 3.6 V. The B port tracks theV_CCB pin supply voltage. The V_CCB pin accepts anysupply voltage between 1.65 V and 5.5 V. Two input supply pins allows for low Voltage bidirectionaltranslation between any of the 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.

When the output-enable (OE) input is low, all outputs are placed in the high-impedance(Hi-Z) state.

To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through apull-down resistor. The minimum value of the resistor is determined by the current-sourcingcapability of the driver.
