The ICL3244E inverting receivers disable during forced
(manual) powerdown, but not during automatic powerdown
(see Table 2). Conversely, the monitor receiver remains
active even during manual powerdown making it extremely
useful for Ring Indicator monitoring. Standard receivers
driving powered down peripherals must be disabled to
prevent current flow through the peripheral’s protection
diodes (see Figures 2 and 3). This renders them useless for
wake up functions, but the corresponding monitor receiver
can be dedicated to this task as shown in Figure 3.
