Description

The devices in this series consist of dual/quad

independent single or dual supply voltage comparators

on a single monolithic substrate. The common mode

input voltage range includes ground even when operated

from a single supply, and the low power supply current

drain makes these comparators suitable for battery

operation. These types were designed to directly

interface with TTL and CMOS, Current drain is

independent of the supply voltage. The outputs can be

connected to other open-collector outputs to achieve

wired-AND relationships.

The LM393 is dual channel version available in 8-pin

SOP package. The LM339 is quad channel version

available in 14-pin SOP package. All devices are

specified for the temperature range of –40°C to +125°C.
