(X2SON)
GND 1 3 3 — Ground
MR N/A N/A 2 I Manual reset. Pull this pin to a logic low to assert the RESET output. After the MR pin is deasserted, the RESET output deasserts after the reset delay (td) elapses.
NC N/A 2 N/A — No internal connection.
RESET 2 1 1 O Active-low reset output. RESET has a push-pull output drive and is capable of directly driving input pins. RESET is low as long as VDD remains below the factory threshold voltage, and until the delay time (td) elapses after VDD rises above the threshold voltage.
Thermal pad N/A Available Available — Connect to ground or to a floating copper plane for mechanical stability.
VDD 3 4 4 I Supply voltage
