Характеристики
MAX214CWI+, Программируемый приемопередатчик интерфейса RS-232The MAX214CWI+ is a programmable DTE/DCE, +5V RS232 transceiver in 28 pin WSOIC package. It provides a complete 8line software-configurable DTE or DCE port RS232 interface. Tx, Rx, RTS, CTS, DTR, DSR, DCD and RI circuits can be configured as either data terminal equipment (DTE) or data circuit-terminating equipment (DCE) using the DTE/DCE control pin. It eliminates the need to swap cables when switching between DTE and DCE configurations. This is useful when, a portable computer is required to communicate with printers, modems and other computers without carrying multiple cables.
