MAX3323 Datasheet PDF

●The MAX3323EEUE+ is a ±15kV ESD-protected RS-232 Transceiver. The MAX3323E 3.0 to 5.5V powered EIA/TIA-232 and V.28/V.24 communications interfaces are designed for multidrop applications with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection. All RS-232 inputs and outputs are protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, ±8kV using the IEC 1000-4-2 contact discharge method and ±15kV using the human body model. The MAX3323E have pin-selectable 5kR/high-impedance RS-232 receivers. This device is capable of receiving data in high-impedance mode. In multidrop applications, one receiver has a 5kR input resistance, while the other receivers are high impedance to ensure the RS-232 standard is observed. The transmitters are enabled by logic control to allow the multiplexing of the inputs to a single UART.
