About the Tibbit #41 block

This Tibbit is based on the MCP23008 8-bit port expander IC from Microchip. Refer to Microchip datasheet for operation details.

This C1 device requires the Tibbit #00-3 to be installed in the neighboring "M" Tibbit socket.

To simplify wiring, Tibbit #41 is supplied with a 200mm WAS-P044 cable.
