... The detector threshold is fixed with high accuracy in the IC and requires no adjustment. The RN5VD Series are operable by a lower voltage than that for the R 5VL Series, and can be driven by a single battery. Two output types, Nch open drain type and CMOS type, are available. Since the package for these ICs are SOT-23-5(Mini-mold)package, high density mounting of the ICs on board is possible ...
