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 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 Receivers, 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.
