Maxim Integrated (MAX3225ECUP+) Transceiver RS232, 3V-5.5V supply,

Product Overview The MAX3225ECUP+ is a ±15KV ESD protected, 1µA, 1Mbps, RS232 transceiver with AutoShutdown Plus in 20 pin TSSOP package. The device is 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces with automatic shutdown/wakeup feature, high data rate capabilities and enhanced electrostatic discharge (ESD) protection. The 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 human body model. The device automatically enters a low power shutdown mode when the RS232 cable is disconnected or the transmitters of the connected peripherals are inactive. The UART driving the transmitter inputs is inactive for more than 30 seconds, it turn on again when the device sense a valid transition at any transmitter or receiver input. AutoShutdown Plus saves power without changes to the existing BIOS or operating system. Two drivers and two receivers READY output is low when charge pumps are disabled in shutdown mode & high when V- goes below -4V Supply voltage range from 3V to 5.5V Operating temperature range from 0°C to 70°C Low dropout transmitter o/p stage enables RS232 performance from 3V-5.5V supply w/ dual charge pump The charge pump requires only four small 0.1µF capacitors for operation from a 3.3V supply Applications Communications & Networking, Portable Devices Product Information Device Type: Transceiver IC Interface Type: RS232 No. of Drivers: 2Drivers No. of Receivers: 2Receivers Supply Voltage Min: 3V Supply Voltage Max: 5.5V Driver Case Style: TSSOP No. of Pins: 20Pins Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited IC Generic Number: MAX3225
