The pin is capable of outputting up to 100mA. Use it as V
RAM and the like.
Backup power supply is connected to this pin.
If a lithium battery is used, insert a resistor in series for safety purposes.
+3V input pin. Connect to a logic power supply.
A delay capacitor is connected to this pin. By connecting a capacitor, it is
possible to delay each output.
Connect to the positive reset input of a microcontroller. The pin is
capable of flowing 1mA sink current.
Reference for all signals.
Connect to the negative reset input of a microcontroller. The pin is
capable of flowing 1mA sink current.
Connect to the Chip Select of RAM. The CS output is at low level in
normal state thereby letting RAM be active. Under failure or backup
condition, the CS output is set to high level, then RAM enters standby
state disabling read/write function. The pin is capable of flowing a 1mA
sink current.
