Stand Alone UART - SI14 IC
14 Bits Serial Input
The SI14 IC is a stand alone UART IC designed to provide 14 bits of input data to connect to RS-232, RS-485, USB, Ethernet or directly to your UART. Inputs can be from switches, relay contacts, logic, optocouplers or a transistor switched to ground. The SI14 has internal pull resistors on the inputs to minimize additional parts. The SI14 IC transmits data anytime the inputs change or after a delay of 100 or 1000 mS. The output of the SI14 is standard asynchronous format, using 8 bits, 1 stop and no parity at 9600 BPS. Other formats and encoding are available, contact the factory. A .1 uF bypass capacitor is suggested across the VDD and VSS pins. The part uses the standard 20 pin .3 inch width SOIC and DIP package.
