General Description
The MAX3316–MAX3319 transceivers have a proprietary
low-dropout transmitter output stage enabling RS-232-
compatible performance from +2.25V to +3.0V with a
dual-charge pump. These devices require only four
0.1F capacitors, and are guaranteed to operate at data
rates up to 460kbps.
The MAX3318/MAX3319 achieve a 1A supply current
using Maxim’s revolutionary AutoShutdown Plus fea-
ture. These devices automatically enter a low-power
shutdown mode when the RS-232 cable is disconnected
or the transmitters of the connected peripherals are inac-
tive 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 MAX3318
is a 2-Tx/2-Rx device while the MAX3319 is a 1-Tx/1-Rx
device. These devices also feature a logic-level output
(READY) that asserts when the charge pump is regulat-
ing and the device is ready to begin transmitting.
The MAX3316/MAX3317 are 2-Tx/2-Rx transceivers. The
MAX3317 features a 1A shutdown mode that can be
entered by driving SHDN low. The MAX3317’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:
MAX3316 (16-pin SSOP and 20-pin TSSOP), MAX3317/
MAX3318 (20-pin SSOP and 20-pin TSSOP), and
MAX3319 (16-pin SSOP).
