Frequently Asked Questions
How should this transceiver be matched to RS-232 interface requirements?
Match it to designs needing a 3-driver line transceiver that supports EIA/TIA-232 and V.28 signaling across a 3 V to 5.5 V supply range.
Which input and current details matter for noisy serial ports?
The Schmitt trigger inputs help with noise margins, and the 0.000001 A maximum high-level input current is useful when checking leakage budgets.
How should layout teams handle the SSOP package choice?
Plan for the 28-pin SSOP footprint identified by R-PDSO-G28, then confirm clearance and assembly constraints before approving obsolete-device replacement orders.
