Stand alone UART - SO14 IC

14 Bits Serial Output

General Description

The SO14 IC is a stand alone UART designed to provide 14 bits of output data to connect to RS-232, RS-485, USB, Ethernet or directly to your UART. Outputs can be used to drive relay contacts, logic, optocouplers or a transistors. The SO14 also provides a pulse output when the OB data bits are received. The serial input to the SO14 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. This part may be paired with the SI14 chip to achieve 14 bits of input and output, except on RS-485 interfaces.

Features:

  • Asynchronous serial input to control for up to 14 bits of data.
  • Output control using RS-232, RS-485, USB or Ethernet or UART.
  • Can drive be used to drive relays, optocouplers, and logic.
  • No external parts required.
  • Low power consumption 5 mA typical.
  • Supply voltage 2.4 to 5.25 volts.
  • All timing internally generated.
  • TTL and CMOS compatible inputs and outputs.
  • Part is in full production.
  • SOIC and DIP 20 Pin Package.
  • ROHS Compliant.
  • Low EMI.
