The 14-TSSOP package (0.173\" body width, 4.40 mm) is a common footprint shared with many logic and comparator parts, so board layout reuse across variants is straightforward. Surface-mount only — no through-hole option. ## Sourcing and lifecycle — still active, no LTB clock ticking The MAX9108EUD+ carries an Active product status and ROHS3 compliance. No last-time-buy notice, no NRND flag. For a BOM line that needs a quad comparator in a 14-TSSOP, this part is a straight drop-in without worrying about a forced redesign next year.","metaTitle":"MAX9108EUD+ Quad Comparator, 25 ns, 14-TSSOP - Maxim","metaDescription":"MAX9108EUD+ quad general-purpose comparator from Maxim. 25 ns propagation delay, 700 µA quiescent, TTL output, 14-TSSOP.

The LM339 uses a 14-DIP or 14-SOIC package with open-collector outputs, while the MAX9108EUD+ uses a 14-TSSOP package with TTL push-pull outputs. The 25 ns propagation delay of the MAX9108EUD+ is significantly faster than the LM339's typical 300 ns, so the electrical characteristics differ enough that a board redesign would be required. The LM339 also operates from a wider supply range (2 V to 36 V or ±18 V) versus the MAX9108EUD+'s 4.5 V to 5.5 V single-supply range."},{"question":"What is the propagation delay of MAX9108EUD+?","answer":"The maximum propagation delay is 25 ns. That is the time from input crossing the threshold to the TTL output changing state. For high-speed comparator applications like overcurrent detection or zero-crossing, this delay is short enough to avoid adding significant latency to the control loop."},{"question":"What is the closest pin-compatible alternative to MAX9108EUD+?","answer":"Within the same Maxim family, the MAX9109 is a similar quad comparator with the same 14-TSSOP footprint and TTL outputs, but it offers a wider supply range (2.7 V to 5.5 V). The MAX9108EUD+ is the 4.5 V to 5.5 V variant. For a direct pin-compatible swap without changing the board layout, the MAX9109EUD+ is the closest alternative, though the supply voltage minimum differs. No other manufacturer's quad comparator in 14-TSSOP with TTL outputs and 25 ns delay is a guaranteed pin-compatible second source without layout verification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9108EUD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9108EUD when reusing this data.
