Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:
V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.

The MAX3316EMAX3319E are 2.5V powered RS-232 compatible transceivers. These devices feature shut-down (MAX3317E), AutoShutdown Plus (MAX3318E/
MAX3319E), and enhanced electrostatic discharge (ESD) protection integrated into the chip. All transmitter outputs and receiver inputs are protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, ±8kV using the IEC 1000-4-2 Contact Discharge method, and ±15kV using the Human Body Model.

All MAX3316EMAX3319E are guaranteed at a data rate of 460kbps. The transceivers have a proprietary low-dropout transmitter output stage enabling RS-232 compatible operation from a +2.25V to +3.0V supply with a dual charge pump. The charge pump requires only four 0.1µF capacitors. The MAX3318E/MAX3319E feature a logic level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting.

The MAX3318E/MAX3319E achieve a 1µA supply current using Maxim's revolutionary AutoShutdown Plus feature. These devices automatically enter a low power shut-down mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiver input. 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 1µA supply current.  These devices are available in space-saving packages: MAX3316E (16-pin SSOP and 20-pin TSSOP), MAX3317E/MAX3318E (20-pin SSOP and 20-pin TSSOP), and MAX3319E (16-pin SSOP).
