SN74AVC4T245PWR Overview
Part: SN74AVC4T245 — Texas Instruments
Type: Dual-Bit Bus Transceiver with Configurable Voltage Translation
Description: This 4-bit noninverting bus transceiver provides configurable voltage translation between two separate power-supply rails (VCCA and VCCB), each operating from 1.2V to 3.6V, enabling universal low-voltage bidirectional translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes, with data rates up to 380 Mbps.
