... AutoShutdown Plus saves power without changes to the existing BIOS or operating system. The MAX3317E also features a 1µA shutdown mode that can be entered by driving SHDN low. The MAX3317E’s receivers remain active while in shutdown mode, allowing external devices such as modems to be monitored using only 1µ ...

... The receivers are rated to receive signals up to ±25V. The MAX3316E/MAX3318E/MAX3319Es’ receivers feature inverting outputs that always remain active (Table 1). The MAX3317E’s receivers have inverting, three-state outputs. In shutdown, the receivers can be active or inactive (Table 2). The MAX3318E/MAX3319E feature an INVALID output that is asserted low when no valid RS-232 voltage levels have been detected on all receiver inputs ...
