LM293D Description

Short technical summary and product information.

The Texas Instruments LM293D is a dual comparator integrated circuit. It is designed to operate from a single power supply over a wide range of voltages, from 2V to 36V, or from dual supplies. Each comparator within the LM293D features two independent inputs and an open-collector output, compatible with TTL, MOS, and CMOS logic levels.

 

Key electrical characteristics include a low input bias current of 0.25µA maximum and a low input offset voltage of 5mV maximum at 30V. The device has a maximum quiescent current of 2.5mA and can provide an output current of 20mA typical. The operating temperature range for the LM293D is -25°C to 85°C.

 

This comparator is housed in an 8-SOIC package with a surface mount type. The 8-SOIC package has a width of 0.154 inches (3.90mm). Its open-collector output allows for wired-AND logic configurations, making it versatile for various circuit designs.

 

The LM293D is suitable for applications requiring precise voltage level detection and comparison. Its wide operating voltage and temperature range, combined with its output compatibility, make it a flexible component for embedded systems and control circuits.
