DESCRIPTION/ORDERING INFORMATION

The MAX3318E is

a dual-driver, dual-receiver, RS-232-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 ±15 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).

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.

The MAX3318E achieves a 1-µA supply current using 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
