Overview
FM3540/60 4/5 Bit Multiplexed, 1 Bit Latched Port with Standard 2-Wire Bus Interface and Non-Volatile Latches October 2001 FM3540/60 4/5 Bit Multiplexed, 1 Bit Latched Port with Standard 2-Wire Bus Interface and Non-Volatile Latches General Description 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 connections to open drain outputs and to eliminate the need for external resistors.
The device supports a choice of either 2.
5V output or Open Drain Output...
