The LM139DRG4 is a quad general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V and draws a typical quiescent current of 500 uA. The device features four independent differential comparators in a single SOIC-14 package. Key electrical specifications include a response time of 300 ns, an input offset voltage of 5 mV, and an input bias current of 25 nA. Each output channel can source up to 6 mA. The component supports rail-to-rail output and functions reliably across an extended temperature range from -55 C to +125 C.
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and material composition. Ensure the selected variant matches the required operating temperature range and package style for your design. Cross-reference the datasheet revision history to validate any recent specification updates before finalizing procurement decisions.
Select this component when multiple independent comparison channels are required in a compact surface-mount footprint. Consider the 300 ns response time and 5 mV input offset voltage for applications requiring moderate speed and precision. Evaluate the 6 mA output drive capability against load requirements to determine if external buffering is necessary for optimal circuit performance.
This part belongs to the LM139 family of quad comparators, which serves as a standard solution for general-purpose analog comparison tasks. It shares functional similarities with other industry-standard parts but offers specific TI manufacturing characteristics. The DRG4 designation indicates a lead-free, RoHS-compliant version packaged in a standard SOIC-14 format suitable for automated assembly processes.
