The input pins of this driver all use Schmitt input. Typical specifications at Tc=25°C are given below. Hysteresis

voltage is 0.3V (VIHa-VILa).

Input pin

Pin 19

The internal impedance, 100kΩ, is designed so that the increase in current is prevented while Pin 19 is open.

The recommended Vref voltage is 0.14V or higher because the output offset voltage of Vref/4.9 amplifier cannot be

controlled down to 0V
