LP265-LP365 Micropower Programmable Quad Comparator
The document describes the National Semiconductor LP265 and LP365 devices, which consist of four independent voltage comparators. These chips can be programmed simultaneously using a single resistor to adjust supply currents, input currents, response times, and output current drives. They support both split and single power supplies over wide voltage ranges.
| Supply Voltage Range (Single) | 4V DC to 36 V DC |
|---|---|
| Supply Voltage Range (Dual) | 2.0 V DC to 18 V DC |
| Low Power Supply Current | 10 mA |
| Input Offset Voltage (Typ) | 6 mV |
| Response Time (Low Power) | 4 ms |
The comparators are programmed by connecting a single resistor between the V CC and I SET pins.
The uncommitted output stages are directly compatible with DTL, TTL, CMOS, MOS, or other special logic families.
