Overview
The LM393DT is a dual-channel voltage comparator integrated circuit manufactured by ROHM Semiconductor. It operates from a single supply voltage ranging from +2V to +36V or dual supplies of ±1V to ±18V. The device features an open-collector output configuration and includes two independent comparators on a single chip. It is housed in an SO Package8 (SOP-J8) with dimensions of 4.90mm x 6.0mm x 1.55mm. The typical supply current is 0.4mA, and the operating temperature range extends from -40°C to +85°C.
Feature Summary
- Operable with a single power supply over a wide voltage range
- Input and output ground sense capability
- Low supply current consumption
- Open collector output structure
Applications
- Consumer Electronics
- Current Sense Application
- Battery Monitor
- Multivibrator
Procurement Notes
Verify that the component matches the specific ROHM Semiconductor manufacturer designation for the LM393DT model. Confirm the package type corresponds to the SO Package8 (SOP-J8) variant as specified in the official datasheet. Ensure the ordering suffix aligns with the required tape and reel or cut tape specifications provided by the supplier.
Selection Notes
Select this component when a low-power, dual-channel comparator is required for single-supply applications. The wide operating voltage range supports various logic levels. Verify that the open-collector output requirement fits the system design, as external pull-up resistors are necessary for high-level output states.
Part Context
This part belongs to the LM393xxx series of monolithic ICs which integrate two independent comparator circuits. It shares functional similarities with other members of the family such as the LM2903xx and LM339xx, though electrical characteristics like supply current may vary between specific sub-models within the broader product line.
Replacement Considerations
Public confirmed substitute part numbers include LM2903DT.
