Dual comparators
BA10393 / BA10393F / BA10393N
The BA10393, BA10393F, and BA10393N are 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 (BA10393), SOP 8-pin (BA10393F), and SIP 8-pin
(BA10393N).

BA10393 / BA10393F BA10393N
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 VCC = 5V)
3) Low input offset voltage. (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 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
(VICM) and the output is left open.
