SP3222E / SP3232E True 3.0V to 5.5V RS-232 Transceivers Description FEATURES The SP3222E and SP3232E series are RS-232 transceiver solutions Meets true EIA/TIA-232-F standards from intended for portable or hand-held applications such as notebook a 3.0V to 5.5V power supply Minimum 120kbps data rate under full load or palmtop computers. The SP3222E / SP3232E series has a high- 1A low power shutdown with receivers efficiency, charge-pump power supply that requires only 0.1F active (SP3222E) capacitors in 3.3V operation. This charge pump allows the SP3222E Interoperable with RS-232 down to a 2.7V / SP3232E series to deliver true RS-232 performance from a single power source power supply ranging from 3.0V to 5.5V. The SP3222E / SP3232E Enhanced ESD specifications: are 2-driver / 2-receiver devices. This series is ideal for portable or 15kV Human Body Model hand-held applications such as notebook or palmtop computers. The 15kV IEC61000-4-2 Air Discharge ESD tolerance of the SP3222E / SP3232E devices are over 15kV 8kV IEC61000-4-2 Contact for both Human Body Model and IEC61000-4-2 Air discharge test Discharge methods. The SP3222E device has a low-power shutdown mode where the devices driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1A.
