... CC uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions. 7 ICL3224, ICL3226, ICL3238, ICL3244 The ICL3238 and ICL3244 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 ...
