EXPLANATION OF TERMINALS
V
IN
and V
BAT
are controlled by means of an internal switch and output through
V
OUT
.
The pin is capable of outputting up to 100 mA. Use it as V
DD
of CMOS 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.
