FUNCTION
Ground reference
Ground reference, device substrate, connect to ground.
Active-low output. RESET remains low while V
CC
is below the reset threshold
voltage, and for 190 ms after V
CC
rises above the reset threshold voltage.
Active-high output. RESET remains high while V
CC
is below the reset threshold, and
for 190 ms after V
CC
rises above the reset threshold.
Active-low input. Reset is asserted whenever this pin is pulled low and remains
asserted for 190 ms after the MR pin goes high. May be left open.
Supply Voltage (+5V, +3.3V, or +2.5V, nominal)
