ST3243C

3 - 5.5 V 400 KBPS RS-232收發(fā)器，支持自動(dòng)斷電，溫度范圍[0℃, 70℃]; ? ESD protection for RS-232 I/O pins \n ?±8 kV IEC61000-4-2 contact discharge \n ?±15 kV IEC61000-4-2 air discharge \n? 1 μA supply current achieved when in auto-power-down \n? 250 kbps minimum guaranteed data rate \n? Guaranteed 6 V/μs slew rate range \n? Guaranteed mouse drive ability \n? 0.1 μF external capacitors \n? Meet EIA/TIA-232 specifications down to 3 V \n? Available in SSOP-28 package;

The ST3243B/ST3243C devices consist of 3 drivers, 5 receivers and a dual charge pump circuit. The devices meet the requirements of EIA/TIA and V.28/V.24 communication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection.\n\n All transmitter outputs and receiver inputs are protected to ±8 kV using IEC61000-4-2 contact discharge and ±15 kV IEC61000-4-2 air discharge.\n\n The receiver R2 is always active to implement a wake-up feature for the serial port.\n\n The ST3243B/ST3243C devices have 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 devices are guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels.\n\n The auto-power-down feature functions when FORCEON is low and FORCEOFFis high. During this mode of operation, if the device does not sense a valid RS-232 signal, the driver outputs are disabled. If FORCEOFFis set low, both drivers and receivers (expert R2B) are shut off, and supply current is reduced to 1 μA. Disconnecting the serial port or turning off the peripheral drives causes the auto-power-down condition to occur.\n\n Auto-power-down can be disabled when FORCEON and FORCEOFFare high, and should be done when driving a serial mouse. With auto-power-down enabled, the device is activated automatically when a valid signal is applied to any receiver input.\n\n Typical application are in notebook, subnotebook, palmtop computers, battery-powered equipment, hand-held equipment, peripherals, and printers.\n\n
