The SP3222EB/SP3232EB series is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222EB/SP3232EB series has a high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3222EB/SP3232EB series to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3222EB/SP3232EB 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/SP3232EB devices are over +/-15kV 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 1μA.
- Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
- 250kbps Transmission Rate Under Load
- 1µA Low-Power Shutdown with Receivers Active
- Interoperable with RS-232 down to +2.7V power source
- Enhanced ESD Specifications:
- ±15kV Human Body Model
- ±15kV IEC1000-4-2 Air Discharge
- ±8kV IEC1000-4-2 Contact Discharge

07/17/2023 | In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023. | PCN & PDN Download |

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps) | Maximum RS-232 Cable Length (ft) |
19200 | 50 |
9600 | 500 |
4800 | 1000 |
2400 | 3000 |
