Receiver hysteresis and signal integrity
The ADM208EARSZ: The 650 mV receiver hysteresis provides noise margin on the RS-232 bus, reducing false triggering from line transients or crosstalk in cable runs up to a few metres at 230 kbps.

Frequently asked questions
How does ADM208EARSZ compare to the through-hole ADM208EANZ?
Both are full-duplex RS-232 transceivers with 4 drivers/4 receivers and 230 kbps data rate. The ADM208EARSZ uses a surface-mount 24-SSOP package, while the ADM208EANZ is through-hole — the board footprint and assembly process differ, but the electrical function is identical.
