________________General Description

____________________________Features

The MAX3316E–MAX3319E 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 15ꢀV

using the IEC 1000-4-2 Air-Gap Discharge method,

8ꢀV using the IEC 1000-4-2 Contact Discharge

method, and 15ꢀV using the ꢁuman ꢂodꢃ Model.

All devices are guaranteed at a data rate of 460ꢀbps.

The transceivers have a proprietarꢃ low-dropout trans-

mitter output stage enabling RS-232 compatible opera-

tion from a +2.25V to +3.0V supplꢃ with a dual charge

pump. The charge pump requires onlꢃ 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 readꢃ to begin

transmitting.

The MAX3318E/MAX3319E achieve a 1µA supplꢃ current

using Maxim’s revolutionarꢃ AutoShutdown Plus feature.

These devices automaticallꢃ 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. Theꢃ turn on again when

theꢃ sense a valid transition at anꢃ transmitter or receiver

input. AutoShutdown Plus saves power without

changes to the existing ꢂIOS or operating sꢃstem. The

MAX3317E also features a 1µA shutdown mode that

can be entered bꢃ driving SHDN low. The MAX3317E’s

receivers remain active while in shutdown mode, allowing

external devices such as modems to be monitored

using onlꢃ 1µA supplꢃ current.
