General Description The MAX3224–MAX3227/MAX3244/MAX3245 are 3V powered EIA/TIA-232 and V.28/V.24 communications interfaces with automatic shutdown/wakeup features and high data-rate capabilities. All devices achieve a 1µA supply current using Maxim’s revolutionary AutoShutdown Plus™ feature. These devices automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive, and the UART driving the transmitter inputs is inactive 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. Next Generation Device Features ♦ For Smaller Packaging: MAX3228/MAX3229: +2.5V to +5.5V RS-232 Transceivers in UCSP™ ♦ For Low-Voltage or Data Cable Applications: MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA, 2 Tx/2 Rx RS-232 Transceivers with ±15kV ESD Protected I/O and Logic Pins ♦ For Integrated ESD Protection: MAX3222E/MAX3232E/MAX3237E/MAX3241E†/MAX3246E: ±15kV ESD-Protected, Down to 10nA, +3.0V to +5.5V, Up to 1Mbps, True RS-232 Transceivers (MAX3246E Available in UCSP) Applications Notebook, Subnotebook, and Palmtop Computers Cellular Phones Battery-Powered Equipment Handheld Equipment Peripherals Printers
1/1 Transceiver Full RS232 16-SSOP
The MAX3226EEAE+T is a ±15KV ESD protected, 1µA, 250Kbps, RS232 transceiver with AutoShutdown Plus in 16 pin SSOP 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 output and receiver input 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.
