LTV-247

LTV-247 is the base ordering code for the Lite-On LTV-247 quad transistor-output optocoupler in SOP-16, verified against the maker’s LTV-2X7 series datasheet (specification DS70-2009-0014, revision D), which carries this bare string as the part number through its package and taping sections. The bare code is the no-mark rank form: it needs no rank suffix to be orderable, and its transfer specification is a current transfer ratio of 50 % to 600 % at 5 mA input current. Verified figures: input forward voltage of 1.2 V typical and 1.4 V maximum at 20 mA, collector-emitter saturation voltage of 0.4 V maximum, collector-emitter breakdown of 80 V minimum, isolation voltage of 3750 Vrms, and collector current of 50 mA maximum per channel, over -55 °C to +110 °C. The selection point is four isolated channels in one 16-pin body for multi-loop feedback and signal transfer in power supplies and industrial controls. Selection advice: the ranked variants of this family (the -B and -GB forms) are separate order codes with narrower transfer bands — an offer of a ranked variant against this code, or of this code against a ranked position, changes the loop gain and must be requalified. Parameters verified against the Lite-On LTV-247 datasheet.
