High-Speed 3.0V to 5.5V,Slew-Rate Controlled RS-485/422
Transceivers with Extended Common-Mode Range
February 2013
FEATURES
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 half-
duplex 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, short-
circuit, or idle (terminated but not driven). The receiver’s worst
case minimum input resistance is at least 90KΩ, supporting up to
224 nodes.
