LM139J

1 Function

1 • Wide power supply range-single power supply: 2v to 36v (tested 30v)-dual power supply: ± 1v to ± 18v (tested ± 15v) • low power supply-current consumption independent of power supply voltage: 0.8 mA (typical) • low input bias current: 25 nA (typical) • low input offset current: 3 nA (typical) • low input offset voltage: 2 mV (typical) • Common mode input voltage range includes ground • Differential input voltage range is equal to the maximum rated supply voltage: ± 36v • Low output saturation voltage • Output compatible with TTL,MOS and CMOS • On products that meet MIL-PRF-38535 requirements, Unless otherwise stated, all parameters will be tested. On all other products, the production process does not necessarily include testing of all parameters.

2 Applications

• Industrial • Automotive-Infotainment and Clusters-Body Control Module • Power Supply Monitoring • Oscillator • Peak Detector • Logic Voltage Conversion

3 Description

LM139-MIL device consists of four independent voltage comparators and is designed to be powered by a single power supply over a wide voltage range. As long as the difference between the two power supplies is 2v to 36v, and VCC is at least 1.5v positive than the input common mode voltage, you can also operate from dual power supplies. The current consumption is independent of the supply voltage. The output can be connected to other open-collector outputs to achieve a line-and relationship. LM139-MIL equipment is characterized by operation in the entire military temperature range of -55°C to 125°C.
