LM239N Description

Short technical summary and product information.

The LM239N from Texas Instruments is a versatile quad differential comparator IC. It is designed for a wide range of applications including level detection, low-level sensing, and memory applications in consumer, automotive, and industrial electronic systems.

This comparator supports single supply operation from 3.0 V to 36 V and split supply operation from ±1.5 V to ±18 V. Key electrical characteristics include low input bias current of 25 nA (typical) and low input offset current of ±5.0 nA (typical). The input common-mode voltage range extends to ground, and it features a low output saturation voltage of 130 mV (typical) at 4.0 mA.

The LM239N is housed in a 14-pin Dual In-line Package (DIP) with a 0.300" lead spacing, suitable for through-hole mounting. It offers TTL and CMOS compatible outputs. The device operates within an ambient temperature range of -25°C to 85°C.
