The LP239 is an obsolete product and is no longer supplied. It is a low-power quadruple differential comparator with a wide supply voltage range and ultralow power supply current drain. It is suitable for various applications, including limit comparators, simple analog-to-digital converters, pulse generators, etc.
The document details three models of low-power quadruple differential comparators: the LP239 (obsolete), LP339, and LP2901. These devices are designed to operate from a single power supply ranging from 3 V to 30 V while drawing typically only 60 µA of drain current. They feature pin-for-pin compatibility with the LM239, LM339, and LM2901 series.
| Supply Voltage Range | 3 V to 30 V |
|---|---|
| Typical Drain Current | 60 µA |
| Output Sink Current (Vo = 2V) | 30 mA |
| Operating Temperature Range (LP2901) | -40°C to 85°C |
No, the LP239 is obsolete and is no longer supplied.
Yes, they are designed specifically to interface with the CMOS logic family.
