概述
Description
74AVC2T245GUX is a dual-supply, bidirectional bus transceiver with two data channels. It translates signals between two voltage domains: A-side pins powered from VCCA and B-side pins powered from VCCB. A single DIR input selects the direction (A→B or B→A), and a common OE tri-states both sides. It provides two 2-bit (two-channel) paths, enabling fast, hardware-level level shifting without extra resistors or buffers. Typical uses include interfacing microcontrollers, memories, or peripherals across different IO voltages and backplane/databus bridging. Benefits: compact 2-channel level shifter, standard CMOS performance, low power, and easy integration. For exact voltage ranges, timing specs, and packaging details (GUX suffix), refer to the datasheet.
