| HI-3182PSx-N, HI-3185PSX-N August 2006 ARINC 429 DIFFERENTIAL LINE DRIVER PIN CONFIGURATION VREF 1 N/C (See Note * ) 2 SYNC 3 DATA (A) 4 14 V1 13 CLOCK 12 DATA (B) 11 CB 10 BOUT 9 +V 8 GND GENERAL DESCRIPTION The HI-3182, and HI-3185 bus interface products are silicon gate CMOS devices designed as a line driver in accordance with the ARINC 429 bus specifications. In addition to being functional upgrades of Holt's HI-8382 product, they are also alternate sources for a variety of similar line driver products from other manufacturers. Inputs are provided for clocking and synchronization. These signals are AND'd with the DATA inputs to enhance system performance and allow the HI-318X series of products 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 differential outputs of the HI-318X series of products are 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. A 37.5 ohm resistor is in series with each ARINC output. In addition the HI-3182 product also has a fuse in series with each output. The HI-318X series of line drivers are intended for use where logic signals must be converted to ARINC 429 levels such as when using an ASIC, the HI-8584/HI-3282/HI-8282A ARINC 429 Serial Transmitter/Dual Receiver, the HI-6010 ARINC 429 Transmitter/Receiver or the HI-8783 ARINC Interface Device. Holt products are readily available for both industrial and military applications. Please contact the Holt Sales Department for additional information.

A ) HOLT INTEGRATED CIRCUITS www.holtic.com 08/06 HI-3182PSx-N, HI-3185PSX-N FUNCTIONAL DESCRIPTION The SYNC and CLOCK inputs establish data synchronization utilizing two AND gates, one for each data input (figure 2). Each logic input is TTL/CMOS compatible. Figure 1 illustrates a typical ARINC 429 bus application. Three power supplies are necessary to operate the HI-318X; 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). 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 CA and CB pins swing between +5V and ground allowing the switching of capacitor values with an external singlesupply analog switch. The ARINC outputs of the HI-3182, are protected by internal fuses capable of sinking between 800 - 900 mA for short periods of time (125ms). The Vref pin has an internal pull-up resistor to V+, allowing the use of a simple external zener diode to set the reference voltage. 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 DATA (A) V1 SYNC CLOCK AOUT +V -V INPUTS DATA (B) CA CB GND TO ARINC BUS BOUT -15V Figure 1.
