Features

The LM293ST features:

Wide operating supply voltage range of 2V to 36V
Dual comparator with open-collector outputs for better performance
Designed for precision voltage monitoring and measurement applications
Low current consumption for energy efficiency
Operating temperature range of -25°C to 85°C

Package

The package type of LM293ST is MSOP8, which is a mini Small Outline Package (SMT) with 8 pins.

Pinout

According to STMicroelectronics' documentation, the LM293ST is a dual comparator in an MSOP8 package. The pin count for this device is 8.

The pin functions are:

Pin 1: VCC (positive supply voltage)
Pin 2: OUTA (output of Comparator A)
Pin 3: INA (input of Comparator A)
Pin 4: GND (ground)
Pin 5: OUTB (output of Comparator B)
Pin 6: INB (input of Comparator B)
Pin 7: NC (no connection)
Pin 8: VCC (positive supply voltage)

Note that the LM293ST has open-collector outputs, which means that the output pins are only active when a pull-up resistor is connected to VCC.

Manufacturer

The manufacturer of the LM293ST is STMicroelectronics, a leading global semiconductor company that designs, develops, manufactures, and markets a wide range of semiconductor products, including microcontrollers, memory devices, logic ICs, and sensors. STMicroelectronics is a publicly traded company listed on the Euronext Paris stock exchange and is one of the largest semiconductor companies in the world.
