MaxLinear SP3222E
The SP3222E and SP3232E series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222E / SP3232E series has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222E / SP3232E series to deliver true RS-232 performance from a single power supply ranging from 3.0V to 5.5V.| Part No. | SP3222E |

DESCRIPTION
The SP3222E / SP3232E 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 SP3222E / 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.FEATURES
● Meets true EIA/TIA-232-F standards from a 3.0V to 5.5V power supply● Minimum 120kbps data rate under full load
● 1μA low power shutdown with receivers active (SP3222E)
● Interoperable with RS-232 down to a 2.7V power source
● Enhanced ESD specifications:
● ±15kV Human Body Model
