描述 Description

This 6-bit noninverting translator uses two separateconfigurable power-supply rails. The A port is designed to trackVCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The Bport is designed to track VCCB. VCCB accepts any supply voltagefrom 1.65V to 5.5V. This allows for universal low-voltagebidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V,3.3V, and 5V voltage nodes. VCCA should not exceed VCCB.When the output-enable(OE) input is low, all outputs are placedin the high-impedance state.The UTXB0106 is designed so that the OE input circuit issupplied by VCCA.This device is fully specified for partial-power-down applicationsusing IOFF. The IOFF circuitry disables the outputs, preventingdamaging current backflow through the device when it is powereddown.To ensure the high-impedance state during power up or powerdown, OE should be tied to GND through a pull-down resistor; theminimum value of the resistor is determined by the current-sourcingcapability of the driver.

特性 Features

1.2V to 3.6V on A port and 1.65V 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, 4μA Max. ICC IOFF Supports Partial-Power-Down Mode Operation
