MaxLinear SP3222E & SP3232E RS-232 Transceivers
MaxLinear SP3222E and SP3232E RS-232 Transceivers are intended for portable or hand-held applications such as notebooks or palmtop computers. The SP3222E and SP3232E have a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the these transceivers to deliver true RS-232 performance from a single power supply ranging from 3.0V to 5.5V. The MaxLinear SP3222E and SP3232E are 2-driver/2-receiver devices. This series is ideal for portable or hand-held applications such as notebooks or palmtop computers.The ESD tolerance of the SP3222E and SP3232E devices is over ±15kV for both the 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 a shutdown, the supply current falls to less than 1µA.
The MaxLinear SP3222E and SP3232E RS-232 Transceivers are available in SSOP, TSSOP, and SOIC package options for design flexibility.
