3.2 Digital I/O
3.2.1 Digital Inputs
The OP6800 has eight digital inputs, IN00–IN07, each with a current-limiting resistor of
27 k
, and protected over a range of –36 V to +36 V. The inputs are all pulled up to +5 V
as shown in Figure 9.
Figure 9. OP6800 Digital Inputs
The OP6800 also has five digital inputs, IN08–IN12, each with a current-limiting resistor
of 12 k
, protected over a range of –25 V to +25 V, and pulled up to +5 V.
The actual switching threshold for IN00–IN12 is approximately 2.40 V. Anything below
this value is a logic 0, and anything above is a logic 1.
IN13–IN17 are connected in parallel with five of the keypad buttons. These inputs are nor-
mally pulled up, but pulling one of these inputs down is the equivalent of pressing the cor-
responding keypad key remotely.
NOTE: Remote keypad signal inputs IN13–IN17 are not protected, and can only
handle a voltage range from 0 to +5 V. These inputs were designed solely to
facilitate a remote keypad, and should not be used for other purposes.
