Part Manufacturer: Maxim


Part Description: MAX3224 MAX3227 MAX3244 MAX3245

Part Details:

19-1289; Rev 3; 9/05 1µA Supply Current, 1Mbps, 3.0V to 5.5V, RS-232 Transceivers with AutoShutdown Plus MAX3224­MAX3227/MAX3244/MAX3245 ________________General Description _Next Generation Device Features The MAX3224­MAX3227/MAX3244/MAX3245 are 3V- For Smaller Packaging: powered EIA/TIA-232 and V.28/V.24 communications MAX3228/MAX3229: +2.5V to +5.5V RS-232 interfaces with automatic shutdown/wakeup features Transceivers in UCSPTM and high data-rate capabilities. For Low-Voltage or Data Cable Applications: All devices achieve a 1µA supply current using Maxim srevolutionary AutoShutdown PlusTM feature. These MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA, devices automatically enter a low-power shutdown 2 Tx/2 Rx RS-232 Transceivers with ±15kV ESD- mode when the RS-232 cable is disconnected or the Protected I/O and Logic Pins transmitters of the connected peripherals are inactive, For Integrated ESD Protection: and the UART driving the transmitter inputs is inactive MAX3222E/MAX3232E/MAX3237E/MAX3241E/ for more than 30 seconds. They turn on again when MAX3246E: ±15kV ESD-Protected, Down to 10nA, they sense a valid transition at any transmitter or receiv-er input. AutoShutdown Plus saves power without +3.0V to +5.5V, Up to 1Mbps, True RS-232 changes to the existing BIOS or operating system. Transceivers (MAX3246E Available in UCSP) The MAX3225/MAX3227/MAX3245 also featureMegaBaudTM operation, guaranteeing 1Mbps for high- _______________Ordering Information speed applications such as communicating with ISDNmodems. The MAX3224/MAX3226/MAX3244 guarantee PKG 250kbps operation. The transceivers have a proprietary PART TEMP RANGE PIN-PACKAGE CODE low-dropout transmitter output stage enabling true RS- M A X3 2 2 4C P P 0°C to +70°C 20 Plastic DIP -- 232 performance from a +3.0V to +5.5V supply with adual charge pump. The charge pump requires only four M AX3224C AP 0°C to +70°C 20 S S OP T4477- 3 small 0.1µF capacitors for operation from a 3.3V supply. M AX3224C TP 0°C to +70°C 20 Thin QFN-EP* T2055-5 The MAX3224­MAX3227 feature a logic-level output
