HI-8592, HI-8593, HI-8594 October, 2010 Single-Rail ARINC 429 Differential Line Driver GENERAL DESCRIPTION PIN CONFIGURATION (TOP VIEW) The HI-8592 bus interface product is a silicon gate CMOS device designed as a line driver in accordance with the ARINC 429 bus specifications. The part includes a negative voltage converter allowing it to operate from a single +5V supply using only two external capacitors. The part also features high-impedance outputs (tri-state) when both data inputs are taken high, allowing multiple line drivers to be connected to a common bus. 14 AMPB V+ 1 13 TXBOUT SLP 2 TX0IN 3 12 AMPA TX1IN 4 11 TXAOUT 10 V- GND 5 The HI-8593 and HI-8594 are reduced pin count versions of HI-8592 which do not incorporate the negative voltage converter. These devices are compatible with Holt’s existing HI-8570 and HI-8571 respectively, with the added advantage of the tri-state outputs. For even smaller board footprint, versions are also available in leadless, surface mount QFN-style packages.

Application Example HOLT INTEGRATED CIRCUITS 3 HI-8592, HI-8593, HI-8594 FUNCTIONAL DESCRIPTION Figure 1 is a block diagram of the line driver. The chip requires a positive 5V supply at V+. The negative 5V supply at V- may be from an external source or may be provided using the on-chip negative rail generator by connecting the two external capacitors, CFLY and COUT. Currents for slope control are set by on-chip resistors. The TX0IN and TX1IN inputs receive logic signals from a control transmitter chip such as the HI-3584. TXAOUT and TXBOUT hold each side of the ARINC bus at Ground until one of the inputs becomes a One. If for example TX1IN goes high, a charging path is enabled to 5V on an “A” side internal capacitor while the “B” side is enabled to -5V. The charging current is selected by the SLP pin. If the SLP pin is high, the capacitor is nominally charged from 10% to 90% in 1.5μs. If SLP is low, the rise and fall times are 10μs. The reduced pin-count HI-8593 and HI-8594 require an external -5V supply. slopes and differentially drives the ARINC line. Current is limited by the series output resistors at each pin. There are no fuses at the outputs of the HI-859x family. The HI-8593 has 37.5 ohms in series with each TXOUT output and the HI-8594 has 5 ohms in series with each AMP output. The AMP outputs are for applications where external series resistance is required, typically for lightning protection devices. Both output types are available on the HI-8592. Holt Application Note AN-300 describes suitable lightning protection schemes. All devices feature tri-stateable outputs to allow multiple line drivers to be connected to the same ARINC 429 bus. Setting TX1IN and TX0IN both to a logic “1” puts the outputs in the high-impedance state. The HI-8592 family of line drivers are built using highspeed CMOS technology. Care should be taken to ensure the V+ and V- supplies are locally decoupled to reduce noise. An application example is shown in Figure 2.

These are stress ratings only. Operation at the limits is not recommended. Note: The HI-8592 family of drivers are available in small-footprint, thermally enhanced SOIC and QFN (chip-scale) packages. These packages include a metal heat sink located on the bottom surface of the device. This heat sink should be soldered down to the printed circuit board for optimum thermal dissipation. The heat sink is electrically isolated from the chip and can be soldered to any ground or power plane. HOLT INTEGRATED CIRCUITS 4 HI-8592, HI-8593, HI-8594 ELECTRICAL CHARACTERISTICS Table 3.
