and the like
Backup power supply input
Backup power supply is connected to this pin
If a lithium battery is used,insert a resistor in series for safety purposes
Power supply input
+5V input pin.Connect to a logic power supply.
Delay capacitor connection pin
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 microcomputer.The pin is capable
of flowing 1mA sink current

Reference for all signals
Connect to the negative reset input of a microcomputer.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
