SLLS687A –OCTOBER 2005–REVISED OCTOBER 2013

2.5-V 460-kbps RS-232 TRANSCEIVER

WITH ±15-kV ESD PROTECTION

Check for Samples: MAX3318

FEATURES

DESCRIPTION

The MAX3318 is a dual-driver, dual-receiver, RS-232

•

ESD Protection for RS-232 I/O Pins

compatible transceiver. The device features auto-

power-down plus and enhanced electrostatic

discharge (ESD) protection integrated into the chip.

Driver output and receiver input are protected to ±8

kV using the IEC 61000-4-2 Air-Gap Discharge

method, ±8 kV using the IEC 61000-4-2 Contact

Discharge method, and ±15 kV using the Human-

Body Model (HBM).

•

300-μA Operating Supply Current

1-μA Low-Power Standby (With Receivers

Active) Mode

•

Designed to Transmit at a Data Rate of

460 kbps

The device operates at a data rate of 460 kbps. The

transceiver has

a proprietary low-dropout driver

output stage enabling RS-232-compatible operation

from a 2.25-V to 3-V supply with a dual charge pump.

The charge pump requires only four 0.1-μF

capacitors and features a logic-level output (READY)

that asserts when the charge pump is regulating and

the device is ready to begin transmitting.

Auto-Power-Down Plus Option Features

Flexible Power-Saving Mode

Operates From a Single 2.25-V to 3-V V_CC

Supply

APPLICATIONS

The MAX3318 achieves a 1-μA supply current using

•

Battery-Powered Systems

PDAs

the

auto-power-down

feature.

This

device

automatically enters a low-power power-down mode

when the RS-232 cable is disconnected or the drivers

of the connected peripherals are inactive for more

than 30 s. The device turns on again when it senses

a valid transition at any driver or receiver input. Auto

power down saves power without changes to the

existing BIOS or operating system.

This device is available in two space-saving

packages: 20-pin SSOP and 20-pin TSSOP.
