MaxLinear | SP3232ECN-L

The SP3232EB series of RS-232 transceiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222EB/3232EB series has a high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3 V operation. This charge pump allows the SP3222EB/3232EB series to deliver true RS- 232 performance from a single power supply ranging from +3.0 V to +5.5 V.

The SP3222EB/ 3232EB 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 SP3222EB/ 3232EB devices are over ±15 kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. The SP3222EB 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 1 μA.

Features:

• Meets true EIA/TIA-232-F Standards from a +3.0 V to +5.5 V power supply
• Minimum 120 Kbps Data Rate Under Full Load
• Interoperable with RS-232 down to +2.7 V power source
• Enhanced ESD Specifications:
• ±15 kV Human Body Model
• ±15 kV IEC1000-4-2 Air Discharge
• ±8 kV IEC1000-4-2 Contact Discharge
