Ground connection.
RESET output remains high while V
CC
is below the reset threshold
and remains so for a fixed time period after V
CC
raises above the
reset threshold.
RESET output remains low while V
CC
is below the reset threshold
and remains so for a fixed time period after V
CC
raises above the
reset threshold.
Supply voltage (+1.2V to +5.5V). Due to extremely low operating
current, place a 10nF capacitor between VCC and GND.
