Overview
MT34013 EIGHT CHANNEL ARINC DECODER • 8/16 bit parallel interface • 3 channels programmable to HIGH/LOW speed data • Single 5V supply with low power consumption < 50mW • Full MIL operating range • Programmable test I/P to all channels • Built in parity and word length error detection VLSI COMPONENTS FOR ARINC 429 DATA TRANSMISSION SYSTEMS 1 MT34013 MAXIMUM RATINGS (Above which the useful life may be impaired) Storage Temperature Temperature (Ambient) under Bias Supply Voltage VDD DC Input Voltage Output Current (Single O/P) Output Current (Total O/P) ELECTRICAL CHARACTERISTICS over operating range PARAMETER IOH IOL VIH VIL IIL IOZ CI CI/O ICC DESCRIPTION Output High Current Output Low Current Input High Voltage Input Low Voltage Input Load Current Output Leakage Current Input Capacitance I/O Capacitance Supply Current - 65ºC to +150ºC - 55ºC to +125ºC -0.

6 9 10 ARINC 429 SERIAL INPUT INTERFACE Interfaces are provided for 8 independent Arinc 429 serial input channels with sufficient digital storage to guarantee no data is lost provided all 8 channels can be accessed within 230µS.
Channels 0,1 & 2 can be programmed for either high or low speed operation.
Channels 3 to 7 are configured for interfacing to low speed Arinc buses only.
Digital Filtering is incorporated on each decoder input port to prevent word corruption due to noise spikes.
(The duration of reject noise spikes is a function of the basic clock period).
Arinc have suggested that the number of labels available to the user can be increased by either using SDI bits 9 and 10 as extra label bits or by using port identification.
Both of these techniques have been accommodated in the design.
