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 and limited rise and fall time (Low EMI). 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 January 2005 TSSOP µTFBGA TFBGA Table 1: Order Codes PACKAGE T&R TSSOP48 TFBGA54 µTFBGA42 µTFBGA42 (*) 74VCXHQ163245TTR 74VCXHQ163245LBR 74VCXHQ163245TBR 74VCXHQ163245R-E (*) Lead-Free Compliant. 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. All floating bus terminals during High Z State don’t need external pull-up or pull-down resistor.
