DESCRIPTION
bs - This IC is intended for two-way asynchronous t(s) communication between data buses, and the direction of data transmission is determined by c DIR input. All inputs are equipped with protection circuits against static discharge and transient excess voltage. All floating bus terminals during High Z State must be held HIGH or LOW.
