LP265
LP265 is Micropower Programmable Quad Comparator manufactured by National Semiconductor.
Description
The LP365 consists of four independent voltage parators The parators can be programmed four at the same time for various supply currents input currents response times and output current drives This is acplished by connecting a single resistor between the VCC and ISET pins These parators can be operated from split power supplies or from a single power supply over a wide range of voltages The input can sense signals at ground level even with single supply operation The unique output NPN transistor stages are unmitted to either power supply They can be connected directly to various logic system supplies so that they are highly flexible to interface with various logic families Application areas include battery power circuits threshold detectors zero crossing detectors simple serial A D converters VCO multivibrators voltage converters power sequencers and high performance V F converters and RTD linearization
Features
Single programming resistor to tailor power consumption input current speed and output current drive capability Wide single supply voltage range or dual supplies (4 VDC to 36 VDC or g 2 0 VDC to g 18 VDC) Low supply current drain (10 m A) and low power consumption (10 m W parator) ISET e 0 5 m A VCC e 5VDC Unmitted output stage selectable output levels Output directly patible with DTL TTL CMOS MOS or other special logic families Input mon-mode range includes ground Differential input voltage equal to the power supply voltage
