Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V, 3.3V/2.5V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation. The A port is designed to track VCCA. The B port is designed to track VCCB. This device is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by CMD-dir/ DATA0-dir/ DAT123-dir inputs. The Bp...
