Product Details

Description



Features:

· Replaces one 1488 and two 1489s
· Conforms to EIA/TIA-232-E
· 3 drivers and 5 receivers
· Flow through pinout
· Failsafe receiver outputs
· 20-pin SOIC package
· LapLink® compatible −200 kbps data rate




Application

· 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 DS14185 is a 3 x 5 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.

Description

The DS14185 is a three driver, five receiver device which conforms to the EIA/TIA-232-E standard.

The flow-through pinout facilitates simple non-crossover board layout. The DS14185 provides a one-chip solution for the common 9-pin serial RS-232 interface between data terminal and data communications equipment.
