Frequently Asked Questions

Which serial-interface designs are a fit for MAX222CDWRG4?

MAX222CDWRG4 is intended for EIA-232-F and TIA-232-F serial links, using 2 drivers and 2 receivers for RS-232 ports in industrial or embedded equipment.

How should the SOIC layout be planned around this transceiver?

The device uses an 18-pin SOIC-style package, so designers should allocate routing for charge-pump capacitors, driver outputs, receiver inputs, and serial connector signals.

What input behavior helps when receiving noisy RS-232 signals?

Its Schmitt trigger input characteristics support cleaner receiver switching, and the listed high level input current maximum of 0.000001 A helps limit input loading.
