Function
Ground connection.
RESET output remains high while V
CC
is below the reset threshold
and remains so for a minimum of 150ms 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 minimum of 150ms after V
CC
raises above the
reset threshold.
Manual reset active low input. A logic low signal on MR asserts a
reset condition. Asserted reset continues as long as MR is low and
for a minimum of 150ms after MR returns high.
Supply voltage (+1.2V to +5.5V). Due to extremely low operating
current, it is recommended to place a 10nF capacitor between V
CC
and GND.
