DESCRIPTION
Low Input Offset Current: ±5 nA
The LM139 series consists of four independent
Offset Voltage: ±3 mV
precision voltage comparators with an offset voltage
Input Common-Mode Voltage Range Includes
specification as low as 2 mV max for all four

comparators. These were designed specifically to
operate from a single power supply over a wide range

ADVANTAGES
The LM139 series was designed to directly interface
with TTL and CMOS. When operated from both plus
