Maxim Integrated
Description : ±15kV ESD-Protected, 3.0V TO 5.5V, Low-Power, up TO 250KBPS, True RS-232 TRANSCEIVER View

General Description
The MAX3384E is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface WITH low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected TO ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.
The TRANSCEIVER has a proprietary low-dropout transmit ter output stage, delivering true RS-232 performance from a +3.0V TO +5.5V supply WITH a dual charge pump. The charge pump requires only four small 0.1µF capaciTOrs for operation from a +3.3V supply. Each device is guaranteed TO run at data rates of 250kbps while maintaining RS-232 output levels.
The MAX3384E has two receivers and two drivers. It features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems.
The MAX3384E is available in a space-saving SSOP package in either the commercial (0°C TO +70°C) or extended temperature (-40°C TO +85°C) range.

Maxim Integrated
Description : +3.0V TO +5.5V, 10nA, 250kbps RS-232 TRANSCEIVERs WITH ±15kV ESD-Protected I/O and Logic Pins View

General Description
The MAX3238 true RS-232 TRANSCEIVER achieves a 1µA supply current WITH Maxim’s revolutionary AuTOShutdown Plus™ feature. When the device does not sense a valid signal transition on either the receiver or transmitter inputs WITHin 30sec, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are inactive. The system turns on again when a valid transition is applied TO any RS-232 receiver or transmitter input, saving power WITHout changes TO the existing BIOS or operating system.

Features
♦ 1µA Supply Current Achieved WITH AuTOShutdown Plus
♦ Guaranteed Data Rate: 250kbps
