ST3241EB

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 autopower-down 250 kbps minimum guaranteed data rate Guaranteed 6 V/ms slew rate range Guaranteed mouse drive ability 0.1 µF external capacitors Meets EIA/TIA-232 specifications down to 3 V Available in SSOP-28 package 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 outputs are always active. www.DataSheet.net/ ■ ■ ■ ■ ■ ■ ■ SSOP-28 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 inputs 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. Table 1. Device summar...
