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. This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by nDIR inputs. The enable inputs nG can be used to disable the device so that the buses are effectively isolated. The A-port interfaces with the 3V bus, the B-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.
