GENERAL DESCRIPTION
The
HI-485x devices are slew-rated controlled TIA-485/TIA-422-B
and ISO 8482:1993 compliant transceivers with extended power-
supply, temperature and 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-4850 has
a half-duplex configuration, and the HI-4851 and HI-4852 are full-
duplex. Slew rates are optimized for data rates below 5 Mbps. 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
