LM393DR2G

LM393DR2G is the tape-and-reel SOIC-8 ordering code for the onsemi LM393 dual comparator; onsemi’s own material-composition listing shows LM393DR2G as Active — and shows the otherwise identical LM393DR2 without the G suffix as Obsolete, so the G (lead-free) suffix is part of the orderable identity, not a decoration. Every figure on this page is onsemi’s: single supply of 2 V to 36 V or dual supplies of ±1 V to ±18 V, supply current of 0.4 mA typical independent of supply voltage, input bias current of 25 nA typical, input offset voltage of 5.0 mV maximum, an input common-mode range that includes ground, and open-collector outputs, in the commercial 0 °C to +70 °C grade. The selection point is the original dual comparator for threshold detection, window comparison and level shifting where the output must pull to a different rail than the inputs are sensing. Selection advice: keep the makers separate in your approved vendor list — the Texas Instruments LM393DR also listed in this catalog is TI’s part with TI’s recommended-supply figures (2 V to 30 V), and the ST LM393DT is a third maker’s code; the three are footprint alternatives to qualify one by one, not a shared specification. Parameters verified against the onsemi LM393 datasheet (ordering information and electrical characteristics) and the onsemi material-composition listing for this code.
