External Control Input HOLD Input
RESET Input
ZERO Input
Connect external signal input to terminals 5, 6, 7, 13, and 16. Terminals 7 and 13
are connected to each other internally.
Connected internally.
Connect hold signal (HOLD) input to terminal 5.
Connect reset signal (RESET) input to terminal 6.
Connect forced-zero signal (ZERO) input to terminal 16.
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.
• Switching load current: 20 mA or greater.
Approximately 5 V is imposed between COM and terminals 5 to 7 with a current
flow of approximately 18 mA (a nominal value) at the time of external input short-
circuiting.
