The SP3232EH is a 2 driver / 2 receiver RS-232 transceiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The data transmission rate of 460kbps can meet the demands of high speed RS-232 applications. This device has a high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3232EH device to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance of the SP3232EH device exceeds +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods.
- Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
- Interoperable with RS-232 down to a +2.7V power source
- Enhanced ESD Specifications:
- +15kV Human Body Model
- +15kV IEC61000-4-2 Air Discharge
- +8kV IEC61000-4-2 Contact Discharge
- 460kbps Minimum Transmission Rate
- Ideal for Handheld, Battery Operated Applications

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 |
