MAX3161E：±15kV ESD保护、+3.0V至+5.5V、10nA、RS-232/RS-485/RS-422多协议收发器

MAX3160E/MAX3161E/MAX3162E是可编程RS-232/RS-485/RS-422多协议收发器。MAX3160E/MAX3161E可通过引脚编程设置为2Tx/2Rx RS-232接口或者单RS-485/RS-422收发器。MAX3162E同时配置为2Tx/2Rx RS-232接口和单RS-485/RS-422收发器。 MAX3160E/MAX3161E/MAX3162E具有增强的静电放电(ESD)保护功能。所有发送器输出和接收器输入可承受±15kV (人体模型)静电冲击。 All devices incorporate a proprietary low-dropout trans- mitter output stage, and an on-board dual charge pump to allow RS-232- and RS-485-/RS-422-compliant 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.
