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

•Operation notes circuits (1) Handling unused
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 (VICM) and the output is left open.
