1 / 15 page November 2007 Rev 4 1/15 15 ST3241EB ST3241EC ±15 kV ESD protected 3 to 5.5 V, 400 kbps, RS-232 transceiver with auto-power-down Features ■ ESD protection for RS-232 I/O pins: ±8 kV IEC 1000-4-2 contact discharge ±15 kV human body model ■ 1 µA supply current achieved when in auto- power-down ■ 250 kbps minimum guaranteed data rate ■ Guaranteed 6 V/ms slew rate range ■ Guaranteed mouse drive ability ■ 0.1 µF external capacitors ■ Meet EIA/TIA-232 specifications down to 3 V ■ Available in SSOP-28 and TSSOP28 packages 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 communication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver input are protected to ±8 kV USING IEC 1000-4-2 contact discharge and ±15 kV 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 3.0 V to 5.5 V supply with a dual charge pump. The device is guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels. It is a complete serial port (3 drivers, 5 receivers) intended for notebook or sub-notebook computers. Receivers R1 and R2 have extra outputs in addition to their standard outputs. These extra output are always active. Typical application are in notebook, sub- notebook, palmtop computers, battery-powered equipment, hand-held equipment, peripherals and printers.
