onsemi Comparators LM239D

The LM239D is a quad comparator designed for use in various electronic applications, including consumer, automotive, and industrial sectors. It operates on a single or split supply and features low input bias current of 25 nA and low input offset current of ¬±5.0 nA, enhancing its performance in precision applications. The device supports a wide input common mode voltage range down to ground and has a low output saturation voltage of 130 mV at 4.0 mA, making it suitable for TTL and CMOS compatibility. The LM239D can handle a maximum power supply voltage of +36 V or ¬±18 V and has a maximum input differential voltage range of 36 V. It is rated for operation in ambient temperatures ranging from -25¬8C to +85¬8C, with a storage temperature range of -65¬8C to +150¬8C. The device also includes ESD protection on its inputs, which increases reliability without compromising functionality. Available in multiple package types, including SOIC-14 and PDIP-14, the LM239D is a versatile choice for engineers seeking reliable comparator solutions.
