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 IC 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 B-port interfaces with the 3V bus, the A-port with the 2.5V and 1.8V bus. All inputs are equipped with protection circuits against static discharge, giving them ±2kV ESD immunity and transient excess voltage.
