Product Description

The LM139J is a low power low offset Voltage Quad Comparator designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage. The LM139J is designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, directly interface with MOS logic.
Wide supply voltage range
25nA Low input biasing current
±5nA Low input offset current
±3mV Offset voltage
Common-mode input voltage range
Differential input voltage range equal to the power supply voltage
Military rated
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
