2. 3 Hysteresis width (V
2. 4 Delay time (t
2. 5 Through-type current
The hysteresis width is the difference between the detection voltage and the release voltage. Setting the
hysteresis width prevents malfunction caused by noise on the input voltage. The hysteresis width is internally
fixed and varies depending on the product type (refer to Table 2).
The delay time (t

The internal delay type products (S-1702Axx, Bxx, Cxx, Dxx, Exx, Fxx, Gxx, Hxx, Jxx, Kxx) have delay time which
is internally fixed.
In external delay type products (S-1702Lxx, Mxx, Nxx, Pxx), the delay time (t

This is the current that flows instantaneously when the voltage detector detects and releases a voltage.
A large through-type current flows in CMOS output products (S-1702xBx, xCx, xEx, xFx, xHx, xJx).
A small through-type current flows in Nch open drain products (S-1702xAx, xDx, xGx).
