23 APPLICATION HINTS R R1 R 5VL R 5VL R FIG.8 FIG.9 1. When R 5VL C (CMOS Output) is used in FIG. 8, this IC may oscillate by the through-type current at the detection when impedance is connected between Power Source and R 5VL Pin.When R 5VL A ( Open Drain Output) is used in FIG. 8, and R becomes excessively large, may be varied because of the voltage drop of the supply current in the IC itself.. The connection as shown in FIG. 9 may cause the oscillation in both R 5VL C (CMOS Output) and R 5VL A ( Open Drain Output). 3
