EVALUATION KIT AVAILABLE MAX3160E/MAX3161E/MAX3162E ±15k V ESD-Protected, +3.0V to +5.5V, 10n A, RS-232/RS-485/ RS-422 Multiprotocol Transceivers General Description The MAX3160E/MAX3161E/MAX3162E are programmable RS-232/RS-485/RS-422 multiprotocol transceivers. The MAX3160E/MAX3161E are pin programmable as a 2Tx/2Rx RS-232 interface or a single RS-485/RS-422 transceiver. The MAX3162E is configured as a 2Tx/2Rx RS-232 interface, and a single RS-485/RS-422 transceiver simultaneously. The MAX3160E/MAX3161E/MAX3162E feature enhanced electrostatic discharge (ESD) protection. All of the transmitter outputs and receiver inputs are protected to ±15k V using the Human Body Model. All devices incorporate a proprietary low-dropout transmitter output stage, and an on-board dual charge pump to allow RS-232- and RS-485-/RS-422-pliant performance from a +3V to +5.5V supply. These devices also feature pin-selectable transmitter slew rates for RS-232 and RS-485/RS-422 modes. Slew-rate limiting minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. Disabling slew-rate limiting allows these devices to transmit at data rates up to 10Mbps in RS-485/RS-422 mode and up to 1Mbps in RS-232 mode. The MAX3160E/MAX3162E offer a flow-through pinout that facilitates board layout. The MAX3160E/ MAX3161E/MAX3162E are available in tiny SSOP packages and operate up to -40°C to +85°C temperature ranges.
