LTC1235
WDI:
Watchdog Input, WDI, is a three level input. Driving
WDI either high or low for longer than the watchdog time-
out period, forces both RESET and WDO low. Floating WDI
disables the Watchdog Timer. The timer resets itself with
each transition of the Watchdog Input (see Figure 11).
WDO:
Watchdog logic output. When the watchdog input
remains either high or low for longer than the watchdog
time-out period, WDO goes low. WDO is set high whenever
there is a transition on the WDI pin, or LOW LINE goes low.
The watchdog timer can be disabled by floating WDI (see
Figure 11).

CE IN:
Logic input to the Chip Enable gating circuit. CE IN
can be derived from microprocessor's address line and/or
decoder output. See Applications Information Section and
Figure 6 for additional information.
CE OUT:
Logic output from the Chip Enable gating circuit.
When V
CC
is above the reset voltage threshold, CE OUT is
a buffered replica of CE IN. When V
CC
is below the reset
voltage threshold CE OUT is forced high (see Figure 6).
