SP3232EEN RS232 Transceiver IC

SP3232EEN True 3.0V to 5.5V RS232 Transceivers SMD IC

The SP3232E is a RS232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222E / SP3232E series has a high efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3 Volt operation. This charge pump allows the SP3232EEN IC to deliver true RS232 performance from a single power supply ranging from 3.0V to 5.5V. The SP3232EEN are 2-driver / 2-receiver devices. This series is ideal for portable or hand-held applications such as notebook or palmtop computers.

The ESD tolerance of the SP3232E devices are over ±15kV for both Human Body Model and IEC61000-4-2 Air discharge test 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 1µA.

• Meets true EIA/TIA-232-F standards from a 3.0V to 5.5V power supply

• 1μA low power shutdown with receivers active (SP3222E)

• Interoperable with RS-232 down to a 2.7V power source

• Minimum 120kbps data rate under full load
