WebTTL integrated circuits assume unconnected inputs to be at logic 1 because the main requirement for driving a TTL input is to pull-down the level to near 0 V which takes about 1 mA per input. Fan-in is the number of physical inputs on a gate. For example, if you need a 2-input AND gate and you have only one input, you need to add logic. WebAccessing TTL Ports Via RS232. Logic levels of pins 2, 3, 4, and 6 can be queried from an attached computer using the RS-232 ‘IN’ command. The output logic level of pin 5 can be set with the RS-232 ‘OUT’ command.
