Quad Voltage Comparators for Industrial,

Commercial and Military Applications

The devices in this series consist of four 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.

Type CA139A, has a lower input offset voltage than the

CA139. Some of the SOIC parts are available on tape and

reel (see Ordering Information table). Replace the M suffix in

the part number with M96 when ordering (e.g.,

CA0239M96).
