1 July /5V, High-Speed RS-485/422 Transceivers with High Temperature Range GENERL SCRIPTION The HI-485xH devices are high-speed slew-rate controlled TI-485/ TI-422- 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 CERP-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 ±2 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 ± 1.5 (=3.15V), and ± 2.0 (= 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 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 200 o C.
