It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. This IC is intended for two-way asynchronous communication between data buses; the direction of data transmission 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 apJuly 2003 1/13 74VCX162245 plications. All inputs and outputs are equipped with protection circuits against static discharge, giving INPUT AND OUTPUT EQUIVALENT CIRCUIT them 2KV ESD immunity and transient excess voltage. All floating bus terminals during High Z State must be held HIGH or LOW.
