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).
Features:-
• Operation from Single or Dual Supplies.
• Common-Mode Input Voltage Range to GND.
• Output Voltage Compatible with TTL, DTL, ECL, MOS and CMOS.
• Differential Input Voltage Range Equal to the Supply Voltage.
• Maximum Input Offset Voltage (VIO).
– CA139A …………………………… 2mV.
– CA139, CA239, CA339…………………. 5mV.
– LM2901…………………………….7mV.
– LM3302……………………………20mV.
• Replacement for Industry Types 139, 239, 339, 139A,2901, 3302.
