LM193D [STMicroelectronics]

LM193D Description

These gadgets are made up of two separate voltage comparators that can work independently from one power source across a wide range of voltages. As long as the difference between the two supplies is 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage, operation from dual supplies is also feasible. The supplied voltage has no effect on the current drain. To create wired-AND relationships, the outputs can be coupled to additional open-collector outputs.

The LM193 is designed to operate between 55°C and 125°C. The operating temperature range of the LM293 and LM293A is 25 °C to 85 °C. The operating temperature range of the LM393 and LM393A is 0°C to 70°C. The LM2903 is designed to operate between 40°C and 125°C.
