Monitored Input Voltage 5. See Table 1 for the input voltage threshold.
Monitored Input Voltage 6. See Table 1 for the input voltage threshold.
Monitored Input Voltage 7. See Table 1 for the input voltage threshold.
Monitored Input Voltage 8. See Table 1 for the input voltage threshold.
Watchdog Timer Input. If WDI remains low or high for longer than the watchdog timeout period,
RESET is asserted and the timer is cleared. The timer also clears whenever a reset is asserted or a
rising or falling edge on WDI is detected. The watchdog timer enters a startup period that allows 54s
for the first transition to occur before a reset. Leave WDI unconnected to disable the watchdog timer.
The WDI open-state detector uses a small 400nA current. Therefore, do not connect WDI to anything
that will source or sink more than 200nA. Note that the leakage current specification for most three-
state drivers exceeds 200nA.

Output 5. When the voltage at IN5 falls below its threshold, OUT5 goes low and stays low until the
voltage at IN5 exceeds its threshold. The open-drain output has a 30µA internal pullup to V
Output 6. When the voltage at IN6 falls below its threshold, OUT6 goes low and stays low until the
voltage at IN6 exceeds its threshold. The open-drain output has a 30µA internal pullup to V
Output 7. When the voltage at IN7 falls below its threshold, OUT7 goes low and stays low until the
voltage at IN7 exceeds its threshold. The open-drain output has a 30µA internal pullup to V
Output 8. When the voltage at IN8 falls below its threshold, OUT8 goes low and stays low until the
voltage at IN8 exceeds its threshold. The open-drain output has a 30µA internal pullup to V
Active-Low Manual Reset Input. Pull MR low to assert RESET low. RESET remains low for the reset
timeout period after MR is deasserted. MR is pulled up to V
Set Reset Timeout Input. Connect a capacitor from SRT to GND to set the reset timeout period. The
reset timeout period can be calculated as follows:
Reset Timeout (s) = 2.06 x 10
