The SN74LS245 is an Octal Bus Transmitter/Receiver designed for
8-line asynchronous 2-way data communication between data buses.
Direction Input (DR) controls transmission of Data from bus A to bus
B or bus B to bus A depending upon its logic level.

The 6N137, HCPL-2601/2611 single-channel and HCPL-2630/2631 dual-channel
optocouplers consist of a 850 nm AlGaAS LED, optically coupled to a very high
speed integrated photodetector logic gate with a strobable output. Th
