MAX3160CAP+T

RS-422/RS-485 接口 IC 3-5.5V 1uA Tcvr Multiprotocol

+3.0V to+5.5V, 1μA, RS-232/ RS-485/422 Multiprotocol Transceivers

General Description MAX3160CAP+T

The MAX3160/MAX3161/MAX3162 are programmable +3V to +5.5V RS-232/RS-485/422 multiprotocol transceivers. The MAX3160/MAX3161 are pin programmable as a 2TX/2RX RS-232 interface or a single RS-485/422 transceiver. The MAX3162 is configured as a 2TX/2RX RS-232 interface and a single RS-485/422 transceiver simultaneously.

Benefits and Features MAX3160CAP+T
