Table 1: Order Codes
This IC is intended for two-way asynchronous
communication between data buses and the
direction of data transmission is determined by
DIR input. The enable input G can be used to
disable the device so that the buses are effectively
isolated.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
All floating bus terminals during High Impedance
State must be held HIGH or LOW.
