of two inputs is ON, otherwise the output is OFF.
NOT
NOT - Boolean logic function is the reverse state of a digital
input if input is ON then output is OFF.
DSW
Digital Switch - Selects Input A for output when digital input
signal (SA) is ON, otherwise output is B.
TRIG Trigger - Turns a logic output ON for one logic scan cycle
when the logic input goes from OFF to ON.
LTCH Latch - Turns a logic output ON when latch input (L) turns
ON and unlatch input is OFF. Output turns OFF when unlatch
input (U) turns ON.
TGFF Toggle Flip Flop - Provides an ON state output when a
digital input goes from OFF to ON and the previous state of
the output was OFF, and an OFF state output when the digital

output was ON.
