Description
The DAQ93P03 is a 6 channel digital sensor
preconditioning circuit to interface external
mechanical switches or inductive/conductive
proximity switches to TTL circuits. The chip itself
consist of internal Schmitt Triggers to shape the
external On-Off level input, moreover, RC filter
function is also integrated inside the chip to eliminate
sharp noises carried by the external sensors. No
external filter should be used for DAQ83Q03 since it
has integrated digital filter itself, but external filter
circuit has to be used for 8253/8254 counters. The
filter function can be achieved by connect filter pins
to the ground of DAQ93P03.
INPUT/OUTPUT DESCRIPTION
