DS14196

· In a typical Data Terminal Equipment (DTE) to Data Circuit-Terminating Equipment (DCE) 9-pin de-facto interface implementation, 2 data lines and 6 control lines are required. The data lines are TXD and RXD. The control lines are RTS, DTR, DSR, DCD, CTS and RI.
· The DS14196 is a 5 x 3 Driver/Receiver and offers a single chip solutuion for this DTE interface. As shown in Figure 5, this interface allows for direct flow-thru interconnect. For a more conservative design, the user may wish to insert ground traces between the signal lines to minimize cross talk.

The DS14196 is a five driver, three receiver device which conforms to the EIA/TIA-232-E and the ITU-T V.28 standards.

The flow-through pinout facilitates simple non-crossover board layout. The DS14196 provides a peripheral side one-chip solution for the common 9-pin serial RS-232 interface between data terminals and data communications equipment.

The DS14196 offers optimum performance when used with the DS14185 3 x 5 Driver/Receiver, a host side one-chip solution for the common 9-pin serial RS-232 interface between data terminals and data communications equipment.
