GND | 2 | 2 | 2 | — | Ground connection |
MR | 3 | — | 4 | I | Manual-reset input. Pull low to force a reset. RESET remains low as long as MR is low and for the time-out period after MR goes high. Leave unconnected or connect to VDD when unused. |
RESET | — | 3 | 3 | O | Active-high reset output. Either push-pull or open-drain output stage. |
RESET | 1 | 1 | 1 | O | Active-low reset output. Either push-pull or open-drain output stage. |
VDD | 5 | 5 | 5 | I | Supply voltage. Powers the device and monitors its own voltage. |
WDI | 4 | 4 | — | I | Watchdog timer input. If WDI remains high or low longer than the time-out period, then reset is triggered. The timer clears when reset is asserted or when WDI sees a rising edge or a falling edge. If unused, the WDI connection must be high impedance to prevent it from causing a reset event. |
