The part in- cludes a negative voltage converter allowing it to oper- ate from a single +5V supply using only two external ca- pacitors. 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. The HI-8593 and HI-8594 are reduced pin count ver- sions 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. Logic inputs feature built-in 2,000V minimum ESD input protection as well as 5V or 3.3V logic level compatibility. Products with 5 Ohm or 37.5 Ohm resistors in series with each ARINC output are available to allow the use of external resistors for lightning protection. The HI-859x series of line drivers are intended for use where logic signals must be converted to ARINC 429 levels such as when using an FPGA or the HI-3584 ARINC 429 Serial Transmitter/Dual Receiver. The family of parts are available in Industrial -40 oC to +85 oC, or Extended, -55oC to +125oC temperature rang- es. Optional burn-in is available on the extended tem- perature range.
