STMicroelectronics lists the ST3232ECDR as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. The part is available through the independent distribution channel; we source and quote it to order against an RFQ.
The ST3232ECDR is pin-compatible with the MAX3232 in the 16-SOIC footprint and shares the same 2/2 driver/receiver count and 250 kbps data rate. 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.

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. The commercial temperature range (0°C to 70°C) suits indoor, conditioned environments.
