OX16C954-TQBG

Product Summary

The OX16C954-TQBG is a Quad UART. It is a single chip solution for 4 channel serial add-in cards. The OX16C954-TQBG is ideally suited to PC applications, such as high-speed multi-port add-in cards that enable PC users to take advantage of the maximum performance of analogue modems or ISDN terminal adapters. It is also suitable for any equipment requiring high speed RS232/RS422/RS485 interfaces. The OX16C954-TQBG supports 9-bit data frames used in multi-drop industrial protocols. It also offers multiple external clock options for isochronous applications, e.g. ISDN, xDSL.
