It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal enviroment for both inputs and outputs. This IC is intended for two-way asynchronous communication beetwen data buses; the direction of data trasmission is determined by DIR input. The two enable inputs nG can be used to disable the device so that the buses are effectively isolated. The device circuits is including 26Ω series resistance in the A port outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped March 1999 1/11 74VCX162245 with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. NOTE: IT IS PROHIBITED TO APPLY A SIGNAL TO A TERMINAL WHEN IT IS IN OUTPUT MODE AND WHEN A BUS TERMINAL IS FLOATING (HIGH IMPEDANCE STATE) IT IS REQUESTED TO FIX THE INPUT LEVEL BY MEANS OF EXTERNAL PULL DOWN OR PULL UP RESISTOR.
