Description
Ground
Reset Output, Open-Drain or Push-Pull, Active-Low.
/RESET changes from HIGH to LOW when Vcc
drops below the selected reset threshold or /MR is
pulled low. /RESET remains LOW for the reset
timeout period after Vcc exceeds the device reset
threshold and /MR is released high.
Reset Output, Push-Pull, Active-High. RESET
changes from LOW to HIGH when the Vcc input
drops below the selected reset threshold or /MR is
pulled low. RESET remains HIGH for the reset
timeout period after Vcc exceeds the device reset
threshold and /MR is released high.
Active-Low Manual Reset Input. Internal 20kΩ pull-
up to Vcc. Pull LOW to force a reset. Reset remains
active as long as MR is LOW and for the reset timeout
period after MR goes HIGH. Leave unconnected or
connect to Vcc if unused

RESET
Adjustable Reset Threshold Input. High-impedance input for reset comparator.
Connect this pin to an external resistive-divider network to set the reset threshold
voltage; the typical threshold is 0.44V. Reset is asserted when RESET-IN is below
the threshold (VCC is not monitored).
Supply Voltage (1.3V to 5.5V)
Ground
Reset Output, Push-Pull, Active-High. RESET changes from LOW to HIGH when
the RESET-IN input drops below the typical reset threshold (0.44V). RESET
remains HIGH for the reset timeout period after RESET-IN exceeds the reset
threshold.
Reset Output, Open-Drain or Push-Pull, Active-Low. /RESET changes from HIGH
to LOW when RESET-IN drops below the typical reset threshold (0.44V). /RESET
remains LOW for the reset timeout period after RESET-IN exceeds the reset
threshold.
