LM339 Time Delay Generator Circuit Diagram and Datasheet
LM339 Time Delay Generator Circuit Diagram and Datasheet - The schematic below appears LM139/339 Time Delay Generator Circuit Diagram.
LM339 ICs are designed to operate from a single power supply over a wide range of voltages since they consist of four independent precision voltage comparators with an offset voltage specification for all four comparators.
According to the LM339 datasheet, these device give advantages such as high precision comparators, eliminates need for dual supplies, power drain suitable for battery operation, compatible with all forms of logic, and allows sensing near ground (GND).
