Quad Voltage Comparators for Industrial, Commercial and Military ApplicationsThe devices in this series consist of four independent singleor dual supply voltage comparators on a single monolithicsubstrate. The common mode input voltage range includesground even when operated from a single supply, and thelow power supply current drain makes these comparatorssuitable for battery operation. These types were designed todirectly interface with TTL and CMOS.Type CA139A, has a lower input offset voltage than theCA139. Some of the SOIC parts are available on tape andreel (see Ordering Information table). Replace the M suffix inthe part number with M96 when ordering (e.g.,CA0239M96).
