FM3540, FM3 Datasheet - Fairchild Semiconductor

FM3540 4/5-Bit Multiplexed 1-Bit Latched Port

The FM3540/60 multiplexes the I-port input signals with two internal non-volatile registers that can be loaded through the serial port. The multiplexer is selected via the serial port and defaults to the I-Port upon power-up. Pull-up resistors are provided on the input port to accommodate connection.
