The HI-8582 design offers many enhancements to the industry standard HI- 8282 architecture. The device provides two receivers each with label recognition, 32 by 32 FIFO, and analog line receiver. Up to 16 labels may be programmed for each receiver. The independent transmitter hasa 32 by 32 FIFO anda built-in line driver. The status of all three FIFOs can be monitored using the external status pins, or by polling the HI-8582’s status register. Other new features includea programmable option of data or parity in the 32nd bit, and the ability to unscramble the 32 bit word. Also, versions are available with different values of input resistance and output resistance to allow users to more easily add external lightning protection circuitry. The device can be used at nonstandard data rates when an option pin, , is invoked. The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers. The databus, and all control signals are CMOS and TTL compatible. The HI-8582 applies the ARINC protocol to the receivers and transmitter. Timing is based ona1 Megahertz clock. Although the line driver sharesa common substrate with the receivers, the design of the physical isolation does not allow parasitic crosstalk, and thereby achieves the same isolation as common hybrid layouts.
