The nominal is tighter, but the absolute-maximum table is where the design lives — page 7 of the datasheet carries the min/max columns. ## Supply rail and logic compatibility For 3.3 V systems, this part will not drive a 3.3 V CMOS input directly without a voltage divider or level shifter — the output high is essentially VCC, so feeding 5 V into a 3.3 V-tolerant pin exceeds the absolute maximum. The input LED forward voltage is 1.55 V typical, driven by a maximum 20 mA DC forward current. ## Package and footprint notes Housed in a 5-lead 6-SOIC (0.173\", 4.40 mm width) surface-mount package, supplier device package 5-SO. The 5-lead variant saves board area compared to an 8-pin DIP while keeping the 3750 Vrms creepage. MSL 3 out of the bag — bake before reflow if the moisture-barrier bag has been open past the floor-life window.","metaTitle":"PS9123-F3-AX Optocoupler, 15 Mbps, Push-Pull Output","metaDescription":"PS9123-F3-AX optocoupler: 15 Mbps data rate, push-pull totem-pole output, 3750 Vrms isolation, 60 ns propagation delay.
