The LM339DBRE4 is a quad general-purpose comparator from Texas Instruments, packing four independent open-collector comparators into a 14-SSOP surface-mount package.
The maximum input offset voltage is 5mV at 30V supply, and the input bias current maxes out at 0.25µA at 5V — tight enough for most sensor-interfacing and window-comparator circuits without extra buffering.
The LM339 family includes many quad-comparator variants with the same pinout. The base product number is LM339, so any LM339 in a 14-SSOP package with the same supply range and open-collector output is a functional drop-in. The LM339DBRE4 is the Tape & Reel variant; the LM339DR (SOIC-14) differs in footprint.
