Both operate from 3 V to 5.5 V. The ST part uses 500 mV receiver hysteresis versus the MAX3232's typical 300 mV — a minor difference that rarely affects interoperability. For a drop-in swap, verify the charge-pump capacitor values against your existing BOM; the ST datasheet recommends 0.1 µF, which matches the MAX3232 typical application."},{"question":"What is the data rate of ST3232ECDR?","answer":"250 kbps."},{"question":"What are the typical applications for ST3232ECDR?","answer":"RS-232 serial ports on embedded controllers, industrial PC COM ports, and point-of-sale terminals that need a level translator between a UART and a DB9 connector.
