General Description

The 26C94 quad universal asynchronous receiver/transmitter (QUART) combines four enhanced Philips Semiconductors industry-standard UARTs with an innovative interrupt scheme that can vastly minimize host processor overhead.

It is implemented using Philips Semiconductors’ high-speed CMOS process that combines small die size and cost with low power consumption.

The operating speed of each receiver and transmitter can be selected independently at one of eighteen fixed baud rates, a 16X clock derived from a programmable counter/timer, or an external 1X or 16X clock.

Key Features

  • New low overhead interrupt control.
  • Four Philips Semiconductors industry-standard UARTs.
  • Eight byte receive FIFO and eight byte transmit FIFO for each UART.
  • Programmable data format:.
  • 5 to 8 data bits plus parity.
  • Odd, even, no parity or force parity.
  • 1, 1.5 or 2 stop bits programmable in 1/16-bit increments.
  • Baud rate for the receiver and transmitter selectable from:.
  • 23 fixed rates: 50 to 230.4K baud Non-stand.
