Through-type current
Through-type current refers to the current which flows instantaneously at the time of detection and release of a voltage
detector. Through-type current is large in CMOS output devices, and also flows to some extent in Nch open-drain output
devices.

Oscillation
In applications where a resistor is connected to the voltage detector input (Figure 8), in the CMOS active low products for
example, the through-type current generated when the output goes from low to high (release) causes a voltage drop equal to
[through-type current]
×
[input resistance] across the resistor. When the resultant input voltage drops below the detection
voltage -V
DET
, the output voltage returns to its low level. In this state, the through-type current and its resultant voltage drop
have disappeared, and the output goes back from low to high. A through-type current is again generated, a voltage drop
appears, and the process repeats. This unstable condition is referred to as oscillation.
