The LM239DG is a single-supply quad Comparator designed for use in level detection, low-level sensing and memory applications. The device offers 130mV typical at 4mA low output saturation voltage, 25nA typical low input bias current and ±5nA typical low input offset current.
Low input offset voltage
Input common mode voltage range to GND
TTL and CMOS compatible
ESD clamps on the inputs increase reliability without affecting device operation
