Holt HI-4853CRH 3.3/5v, high-speed rs-485/422 transceivers with Datasheet

3.3/5V, High-Speed RS-485/422 Transceivers with
High Temperature Range
February 2013
GENERAL DESCRIPTION
The HI-485xH devices are high-speed slew-rate controlled TIA-485/
TIA-422-B and ISO 8482:1993 compliant transceivers with
extended temperature ranges of -55˚C to 175˚C for plastic
packages and -55˚C to 200˚C for the ceramic CERDIP-8 package.
The devices can operate over an extended supply (3.15V to 5.5V)
and extended receiver common-mode range for high temperature
and industrial control applications. The receiver input commonmode range of [-12, 15]V and ±20V for the half and full duplex
configurations respectively, is valid over the full supply and
temperature specification. The HI-4853H has a half-duplex
configuration, and the HI-4854H and HI-4855H are full-duplex. Slew
rates are optimized for data rates below 25Mbps. The drivers slewrate 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=3.15V), and ± 2.00V
(VDD= 4.5V) output levels at an extended temperature range of
-55°C to +200°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 70KΩ at 200oC.

DESCRIPTION
Receiver Output. If VID ≥ -50mV, then RO is high. If VID < -150mV then RO is low. If the
bus is shorted, open or terminated but not driven by another terminal, RO will be high.
