The
CO393 is dual comparators with open-collector output which allows wired OR connections.
The operating power supply voltage ranges from 2 to 36V for a single power supply and 1 to 18V for a dual
power supply. The packages are as follows: DIP 8-pin, SOP 8-pin.

CO393
1) Wide operating voltage range.
(Single power supply: 2 to 36V, dual power supply:
1 to 18V)
2) Low current dissipation. (0.4mA typ. at V
CC
= 5V)
3) Low input offset current. (25nA typ. at V
CC
= 5V) and
low input offset voltage. (typically 1.0mV at V
CC
=
5V)
4) Wide common-mode input voltage. (0 to V
CC
1.5V)
5) Open collector output.
6) Compatible with 393 comparators from other manu-
facturers.

Operation notes
(1) Handling unused circuits
If a circuit is not in use, we recommend connecting it
as shown in Figure 7, so that its input is connected to
the potential within the in-phase input voltage range
(V
ICM
) and the output is left open.
