Product Summary

The OX16PCI954-TQA1G is a single chip solution for PCI-based serial and parallel expansion add-in cards. It is a dual function PCI device, where function 0 offers four ultra-high performance OX16C950 UARTs, and function 1 is configurable to offer either an 8 bit Local Bus or a bidirectional parallel port. Each channel in the OX16PCI954-TQA1G, the fastest available PC-compatible UART, offers data rates up to 15Mbps and 128-deep transmitter and receiver FIFOs. The OX16PCI954-TQA1G also provides an IEEE1284 EPP parallel port which fully supports the existing Centronics interface.

Parametrics

OX16PCI954-TQA1G absolute maximum ratings: (1)DC supply voltage:4.5V to 5.5V ; (2)Temperature:0℃ to 70℃.
