________________General Description
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 ±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 devices are guaranteed at a data rate of 460kbps.
The transceivers have a proprietary low-dropout trans-
mitter output stage enabling RS-232 compatible opera-
tion from a +2.25V to +3.0V supply with a dual charge
pump. The charge pump requires only four 0.1F
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 1A 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 1A 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 1A 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).
