Product Overview
SN74AVC4T245PWR from TI is a 4-bit dual-supply voltage-level translator with 3-state outputs. 1.2-3.6V on each side. 200Mbps. Direction control. TSSOP-16.
Working Principle
Dual-supply: A-port referenced to VCCA, B-port to VCCB. DIR pin controls direction (A-to-B or B-to-A). OE enables 3-state. 200Mbps data rate. 1.2V minimum supply for sub-1.8V logic.
