The LM393PWR is a dual differential analog comparator manufactured by Texas Instruments, housed in an 8-TSSOP surface-mount package. It operates on a single or dual power supply ranging from 2V to 36V (±1V to ±18V). The device features open-collector rail-to-rail outputs capable of sinking up to 20mA per channel. Key electrical specifications include a maximum input offset voltage of 5mV at 30V and a maximum input bias current of 0.25µA at 5V. The quiescent supply current is typically 2.5mA. It functions within a commercial temperature range of 0°C to 70°C.
Verify the specific suffix PWR indicates the TSSOP-8 package variant distinct from SOIC or DIP versions. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required tape-and-reel quantity if automated assembly is intended. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to final procurement.
Select this component when a low-cost, general-purpose dual comparator is required in a compact surface-mount form factor. The wide supply voltage range suits both battery-powered and standard logic-level systems. Verify that the open-collector output requirement aligns with the pull-up resistor needs of the downstream circuitry. Consider thermal performance within the 0°C to 70°C range for the target environment.
This device belongs to the LM393 family of dual comparators, widely used in industrial and consumer electronics. It shares functional similarities with the LM2903 and LM193, differing primarily in manufacturing grade and specific parameter tolerances. The TSSOP packaging offers space savings compared to traditional through-hole options while maintaining standard pin configurations for easy board layout transitions.
