The LM339N is a quad differential comparator in 14 pin DIP package. This device consists of four independent voltage comparators that are designed to operate from single power supply over wide range of voltages. LM339N can operate with dual power supply as long as difference between two supplies is 2V to 36V and VCC is at least 1.5V more positive than input common mode voltage. Current drain is independent of supply voltage and outputs can be connected to other open collector outputs to achieve wired AND relationships.
Single supply range from 2V to 36V and dual supplies range from ±1V to ±18V
Low drain supply current is typically 0.8mA (independent of supply voltage)
Response time of 0.3µs (TTL level input step)
Low input bias current is -25nA
Low input offset voltage is 2mV
Common mode input voltage range includes ground
Differential input voltage range equal to maximum rated supply voltage of ±36V
Low output saturation voltage
Output compatible with TTL, MOS and CMOS
Operating temperature range from 0°C to 70°C
This device has limited built-in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
