Hello TI,
I am looking for major technical differences between below mentioned part numbers of RS-232 transceiver ICs. I could see only the operating temperature is different or am I overlooking something. Kindly let me know are there any major differences between two part numbers and reason behind having two different series of part numbers for same specifications and functionality.
1.MAX3232MPWREP
2.TRS3232EQPWRQ1
Best Regards,
Manoj.
Hi Manoj,
In general Clemens is correct - MAX and TRS devices with the same following part numbers are more/less identical and can be used to replace each other.
However in this specific case there are a couple differences between devices mainly because of their operational ranges and ESD ratings - but beyond those they are basically very similar devices.
1. MAX3232MPWREP is a military grade Enhanced Product - which basically means it adds the following value to the part (from the MAX3232-EP datasheet):
This is not offered for the TRS device as it is not an EP device.
2. TRS device is Q1 (automotive qualified) so the temperature range is actually lower on this device (only -40C to 125C instead of -55C to 125C) also it has enhanced ESD protection (where the "E" suffix comes from) - which includes the following ESD ratings:
which are not included on MAX3232-EP
Please let me know if you have any other questions!
Best,
Parker Dodson
