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 common- mode 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 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.
