This data sheet details the features and functions of the MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E +3.0V powered EIA/TIA-232 and V.28/V.24 communication interface devices. These devices feature low power consumption, high data rates, and enhanced electrostatic discharge (ESD) protection.
The Maxim MAX3222E, MAX3232E, MAX3237E, MAX3241E, and MAX3246E are low‑power, high‑speed RS‑232 transceiver devices. They operate from a 3.0 V to 5.5 V supply, provide true RS‑232 voltage levels, and support data rates up to 1 Mbps in MegaBaud mode. Enhanced ESD protection safeguards all I/O pins to +15 kV (Human Body Model).
These devices are offered in compact SO, SSOP, TQFN, TSSOP, and ultra‑small 6 × 6 UCSP packages, making them suitable for space‑constrained applications such as notebooks, smartphones, and battery‑powered equipment. Shutdown mode reduces quiescent current to the nanoampere range while keeping receivers active for monitoring.
