High-Speed 3.0V to 5.5V,Slew-Rate Controlled RS-485/422

Transceivers with Extended Common-Mode Range

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.

DESCRIPTION

Receiver Output. If

ID

≥

-50mV, then RO is high. If V

ID

< -150mV then RO is low. If the

bus is shorted, open or terminated but not driven by another terminal, RO will be high.

Receiver Enable. RE=

Low enables the receiver. RE High forces the receiver output

(RO) into a high impedance state. Internal 450KΩ pull-down resistor

Driver Enable. DE = high enables the driver. DE = low will force the driver output into

__

a high impedance state and the device will function as a line receiver if RE is also low.
