The SN74LVCR16245A device is designed for asynchronous communication between data buses. All inputs and outputs have equivalent 26-Ω resistors that will slow the edges of the output and reduce switching noise caused by long capacitive etch runs or cables. This device can be used as two 8-bit transceivers or one 16-bit transceiver. Active bus-hold circuitr...
