GENERAL DESCRIPTION：

The HI-485x devices are high-speed slew-rated controlled TIA-485/TIA-422-B and ISO 8482:1993 compliant transceivers with extended receiver common-mode range for avionic and industrial control applications. The devices can operate over an extended supply (3.0V to 5.5V) and temperature (-55˚C to 125˚C) range. The receiver input common-mode range of [-15, 20]V and ±24V for the half and full duplex configurations respectively, is valid over the full supply and temperature specification. The HI-4853 has a halfduplex configuration, and the HI-4854 and HI-4855 are full-duplex. Slew rates are optimized for data rates below 25Mbps. The drivers slew-rate control and pre-emphasis reduces high-frequency components in the output signal transitions and also compensates for impedance mismatch. These features provide optimum EMI and jitter performance, essential in EMI sensitive environments and high-integrity data link applications such as in aerospace and industrial controls.

The devices deliver at least ± 1.50V (VDD=3.0V), and ± 2.45V (VDD= 4.5V) output levels at an extended temperature range of -55°C to +125°C into a differential load of 54Ω and 50pF.

The receiver offers true Fail-Safe operation, providing a guaranteed logic high on RO when the bus is open-circuit, shortcircuit, or idle (terminated but not driven). The receiver's worst case minimum input resistance is at least 90KΩ, supporting up to 224 nodes.
