HI-8382, HI-8383 August 2006 ARINC 429 DIFFERENTIAL LINE DRIVER GENERAL DESCRIPTION PIN CONFIGURATION The HI-8382 and HI-8383 bus interface products are silicon gate CMOS devices designed as a line driver in accordance with the ARINC 429 bus specifications. VREF 1 The differential outputs of the HI-8382 are independently programmable to either the high speed or low speed ARINC 429 output rise and fall time specifications through the use of two external capacitors. The output voltage swing is also adjustable by the application of an external voltage to the VREF input. The HI-8382 has on-chip Zener diodes in series with a fuse to each differential output protecting the ARINC bus from an overvoltage failure. The outputs each have a series resistance of 37.5 ohms. The HI-8383 is identical to the HI8382 except that the series resistors are 13 ohms and the overvoltage protection circuitry has been eliminated. 16 V1 STROBE 2 15 N/C SYNC 3 Inputs are provided for clocking and synchronization. These signals are AND'd with the DATA inputs to enhance system performance and allow the HI-8382 to be used in a variety of applications. Both logic and synchronization inputs feature built-in 2,000V minimum ESD input protection as well as TTL and CMOS compatibility.

The SYNC and CLOCK inputs establish data synchronization utilizing two AND gates, one for each data input. Each logic input, including the power enable (STROBE) input, are TTL/CMOS compatible. Besides reducing chip current drain, STROBE also floats each output. However the overvoltage fuses and diodes of the HI-8382 are not switched out. Both ARINC outputs of the HI-8382 are protected by internal fuses capable of sinking between 800 - 900 mA for short periods of time (125µs). Figure 1 illustrates a typical ARINC 429 bus application. Three power supplies are necessary to operate the HI-8382; typically +15V, -15V and +5V. The chip also works with ±12V supplies. The +5V supply can also provide a reference voltage that determines the output voltage swing. The differential output voltage swing will equal 2VREF. If a value of VREF other than +5V is needed, a separate +5V power supply is required for pin V1. With the DATA (A) input at a logic high and DATA (B) input at a logic low, AOUT will switch to the +VREF rail and BOUT will switch to the -VREF rail (ARINC HIGH state). With both data input signals at a logic low state, the outputs will both switch to 0V (ARINC NULL state). POWER SUPPLY SEQUENCING The power supplies should be controlled to prevent large currents during supply turn-on and turn-off. The recommended sequence is +V followed by V1, always ensuring that +V is the most positive supply. The -V supply is not critical and can be asserted at any time. +5V +15V VREF V1 SYNC CLOCK DATA (A) AOUT +V INPUTS The driver output impedance, ROUT, is nominally 75 ohms. The rise and fall times of the outputs can be calibrated through the selection of two external capacitor values that are connected to the CA and CB input pins. Typical values for high-speed operation (100KBPS) are CA = CB = 75pF and for low-speed operation (12.5 to 14KBPS) CA = CB = 500pF. The driver can be externally powered down by applying a logic high to the STROBE input pin. If this feature is not being used, the pin should be tied to ground. The CA and CB pins are inputs to unity gain amplifiers. Therefore they must be allowed to swing to -5V. Provision to VREF +V TO ARINC BUS DATA (B) CA CB STROBE GND -V BOUT -15V Figure 1.

All data taken in still air on devices soldered to a single layer copper PCB (3" X 4.5" X .062"). 2. At 100% duty cycle, 15V power supplies. For 12V power supplies multiply all tabulated values by 0.8. 3. Low Speed: Data Rate = 12.5 Kbps, Load: R = 400 Ohms, C = 30 nF. 4. High Speed: Data Rate = 100 Kbps, Load: R = 400 Ohms, C = 10 nF. Data not presented for C = 30 nF as this is considered unrealistic for high speed operation. 5. Similar results would be obtained with AOUT shorted to BOUT. 6. For applications requiring survival with continuous short circuit, operation above Tj = 175°C is not recommended. 7. Data will vary depending on air flow and the method of heat sinking employed.
