UNTB0102中文资料Dual supply translating transceiver; auto direction sensing数据手册UTC规格书

描述 Description

The UNTB0102 is a 2-bit, dual supply translating transceiverwith auto direction sensing, that enables bidirectional voltage leveltranslation. It

特性 Features

two 2-bit input-output ports (An and Bn), oneoutput enable input (OE) and two supply pins (VCCA and VCCB).VCCA can be supplied at any voltage between 1.2V and 3.6V andVCCB can be supplied at any voltage between 1.65V and 5.5V,making the device suitable for translating between any of the lowvoltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V).Pins An and OE are referenced to VCCA and pins Bn arereferenced to VCCB. A LOW level at pin OE causes the outputs toassume a high-impedance OFF-state. This device is fully specifiedfor partial power-down applications using IOFF. The IOFF circuitrydisables the output, preventing the damaging backflow currentthrough the device when it is powered down. FEATURES  1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port IOFF circuitry provides partial Power-down mode operation Inputs accept voltages up to 5.5V
