HI-3185PSx-N

Note 1. Heatsinking may be required for continuous Output Short Circuit at +125°C and for 100KBPS at +125°C.
Note 2. The fuses used for Output Overvoltage Protection may be blown by the presence of a voltage at either output that is greater than ±12.0V with respect to GND. (HI-3182 only)
NOTE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The HI-3182, and HI-3185 bus interface products are silicon gateCMOSdevices 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 of  HI-3182, and HI-3185  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 TTLandCMOScompatibility.

 The differential outputs of the HI-3182, and HI-3185  products are programmable to either the high speed or low speedARINC 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-3182, and HI-3185  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. HI-3182 product also has a
