... CC -25V ≤ V FIGURE 1. INVERTING RECEIVER CONNECTIONS The ISL4241E inverting receivers disable only when EN is driven high. ISL4243E receivers disable during forced (manual) powerdown, but not during automatic powerdown (see Table 2). ISL424XE monitor receivers remain active even during manual powerdown, making them extremely useful for Ring Indicator monitoring ...

... Most devices in the ISL424XE family provide pins that allow the user to force the IC into the low power, standby state. On the ISL4241E, the powerdown control is via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into it’s powerdown state. Connect SHDN to V function isn’ ...

... Figure 5 illustrates a circuit that keeps the ISL4243E from initiating automatic powerdown for 100ms after powering up. This gives the slow-to-wake peripheral circuit time to reestablish valid RS-232 output levels. 8 ISL4241E, ISL4243E POWER MANAGEMENT FIGURE 5.
