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, 1.8V/1.4V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation. The input tolerant buffers allow to translate VCCB compatible signals and greater signals than VCCB up/down to VCCA. All inputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.
