VCC
Resistance connecting pin for
reference current source of clamp
pulse output circuit, and connects 12
kΩ resistance to GND. When a 12 kΩ
resistance is connected, a 100 µA
current flows through this pin (pulse
width is approximately 300 ns).
Clamp pulse output pulse width is
varied by changing the value of the
resistance.
