Part Number: MAX3238
Other Parts Discussed in Thread: MAX3232, MAX3232E

Dear Team,

Currently, the customer is using SP3232 for 4 output application.

I find MAX3238, but this one is very old solution.

Do you have more up to date solution?

It will be highly appreciated if you can also provide the comparison table between the device you suggest compare to SP3232.

Dear Team,

It seems SP3232 is 2 port and P2P with MAX3232.

Do you have comparison table?

Kevin,

A feature of SP3232E family is that the devices works with 2.7V supply, although the output voltage cannot reach 5V (RS-232 standard). Quote from the datasheet: “Driver outputs will meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V”. Other than this, two devices have very similar electrical characteristics.

Family name	SP3232E	MAX3232E
Speed grades	235kbps	250kbps
Supply range (nom.)	3.0V-5.5V	3.0-5.5V
Supply tolerance	10%	10%
HBM ESD	15kV	15kV
IEC ESD contact discharge	8kV	8kV
IEC ESD air gap discharge	15kV	15kV
Driver output abs max	+-13.2V	+-13.2V
Rin abs max range	+-15V	+-25V
Icc (device on, no load)	300uA	300uA
Temperature range	0⁰C to 70⁰C	0⁰C to 70⁰C

Please let me know if you have more questions.
