UTXB0102中文资料2-Bit Bidirectional Voltage-Level Translator With Auto DirectionSensing数据手册UTC规格书

描述 Description

The UTXB0102 device is a 2-bit noninverting translator that usestwo separate configurable power-supply rails. The A port is designedto track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. TheB port is designed to track VCCB. VCCB accepts any supply voltage from1.65V to 5.5V. This allows for universal low-voltage bidirectionaltranslation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5Vvoltage nodes. VCCA must not exceed VCCB.When the output-enable (OE) input is low, all outputs are placed inthe high-impedance state.This device is fully specified for partial-power-down applicationsusing IOFF. The IOFF circuitry disables the outputs when the device ispowered down. This inhibits current backflow into the device whichprevents damage to the device.OE must be tied to GND through a pull-down resistor to assure thehigh-impedance state during power up or power down; the minimumvalue of the resistor is determined by the current-sourcing capability ofthe 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
