ST3241E

ST3241E ±15KV ESD PROTECTED 3 TO 5.5V, 400KBPS, RS-232 TRANSCEIVER WITH AUTO-POWERDOWN s s s s s s s s ESD PROTECTION FOR RS-232 I/O PINS: ±8KV IEC 1000-4-2 CONTACT DISCHARGE ±15KV HUMAN BODY MODEL 1µA SUPPLY CURRENT ACHIEVED WHEN IN AUTO-POWERDOWN 250Kbps MINIMUM GUARANTEED DATA RATE GUARANTEED 6V/µs SLEW RATE RANGE GUARANTEED MOUSE DRIVEABILITY 0.1µF EXTERNAL CAPACITORS MEET EIA/TIA-232 SPECIFICATIONS DOWN TO 3V AVAILABLE IN SO-28, SSOP28 AND TSSOP28 PACKAGES SSOP SOP DESCRIPTION The ST3241E device consists of 3 drivers, 5 receivers and a dual charge-pump circuit. The device meets the requirements of EIA/TIA and V.28/V.24 comunication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver input are protected to ±8KV USING IEC 1000-4-2 contact discharge and ±15KV using the Human Body Model. The receiver R2 is always active to implement a wake-up feature for serial port. The ST3241E has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. TSSOP It is a complete serial port (3 drivers, 5 receivers) intended for notebook or subnotebook computers. Receivers R1 and R2 have extra outputs in addition to their standard outputs. These extra outputa are always active. Typical application are in notebook, subnotebook, ...
