RESET Input
Connect external signal input to terminals 5 to 7.
Connect hold signal (HOLD) input to terminal 5.
Connect reset signal (RESET) input to terminal 6.
The transistor satisfying the following conditions must be used to input open col-
lector external signals.
• Residual voltage with transistor turned on: 3 V max.
• Current leakage with transistor turned off: 1.5 mA max.
Approximately 5 V is imposed between COM and terminals 5 and 6 with a cur-
rent flow of approximately 18 mA (a nominal value) at the time of external input
short-circuiting.
