Each of the four comparators can sink up to 20 mA typical at the output. The open-collector output stage lets you pull up to a voltage independent of the comparator supply — useful for interfacing 5 V logic from a 12 V-powered comparator, or driving a small relay coil directly without a buffer transistor. The quiescent current draw is 2.5 mA max across all four channels. That keeps the thermal load low in the 14-TSSOP package, which has no exposed pad — the copper pour on the PCB is the only heat path. This part belongs in benchtop instruments, office peripherals, appliance control boards, and similar indoor environments.","metaTitle":"LM339PWRE4 Quad Differential Comparator, 14-TSSOP, 2V-30V","metaDescription":"TI LM339PWRE4 quad differential comparator in 14-TSSOP.

The LM339PWRE4 comes in a 14-TSSOP (4.40 mm width), while the LM339DR is in a 14-SOIC. The pin functions are the same — the standard LM339 quad-comparator pinout — so the electrical replacement is direct. The PCB footprint, however, is different: TSSOP has a tighter 0.65 mm lead pitch versus SOIC's 1.27 mm. If the board is laid out for SOIC, the TSSOP part will not fit without a redesign or an adapter. Check the existing board's pad pattern before ordering."},{"question":"What is the typical power consumption of LM339PWRE4?","answer":"The maximum quiescent current for all four comparators combined is 2.5 mA. At a 5 V supply, that is about 12.5 mW worst-case — negligible in most designs. The actual power draw depends on the output load current, which can add up to 20 mA per channel when the output is sinking."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM339PWRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM339PWRE4 when reusing this data.
