MAX214 Datasheet | Maxim Integrated

Description The MAX214 +5V RS-232 transceiver provides a plete, 8-line, software-configurable, DTE or DCE port RS-232 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. The MAX214 eliminates the need to swap cables when switching between DTE and DCE configurations. ____________________________Features o Eliminates Null Modem Cables o Programmable DTE or DCE Serial Port o 1µF Charge-Pump Capacitors o 116kbps Data Rate- Guaranteed o 20µA Shutdown Mode o Receivers Active in Shutdown ________________________Applications AT-patible Laptop puters AT-patible Desktop puters Modems, Printers, and Other Peripherals ______________Ordering Information PART MAX214CPI MAX214CWI TEMP.
