■ Low input offset voltage
■ Input common-mode voltage range includes
GND
■ Low output saturation voltage 150 mV typical
■ Output compatible with TTL, MOS and CMOS
■ High input impedance: 10
12
Ω typical
■ Fast response time: 200 ns typ for TTL level
input step
Applications
■ Battery powered electronics
■ General-purpose portable device
■ General-purpose low voltage application
Description
These devices consist of two independent
precision voltage comparators, designed to
operate with single or dual supplies.
These differential comparators use the
STMicroelectronics silicon lin MOS process giving
them an excellent consumption-speed ratio.
These devices are ideally suited for low
consumption applications.
