Aeroflex introduces rad-hard transceiver for multipoint RS485 applications
PLAINVIEW, N.Y., 14 March 2008.Aeroflex Plainview in Plainview, N.Y., is introducing a radiation-hardened monolithic dual transceiver called the RadHard ACT4485 for multipoint data transmission RS485 applications.
The ACT4485 meets TIA/EIA-485 that specifies low-voltage differential signaling drivers and receivers for data interchange across half-duplex or multipoint data bus structures.
The ACT4485 is designed to withstand 100 kilorads total-dose radiation, is powered by one 5-volt power supply, and comes in an 18-lead flatpack. The receiver has a fail-safe condition to guarantee high output when the bus is open or shorted.
The driver maintains high impedance in tri-state or with power off supporting as many as 32 bus transceivers. Manufactured in Aeroflex Plainview's Mil-PRF-38534 certified manufacturing facility, the transceiver is built with dielectrically isolated bipolar technology, operates in the full military temperature range of -55 to 125 degrees Celsius. The devices are screened to MIL-PRF-38534, Class K.
