General Description
The CT2542 contains 2 transceivers, 2 encoder/decoders, bit processors and complete Remote Terminal (RT)
logic. The device is constructed using Aeroflex advanced VLSI custom chip and hybrid technology. It
functions as a complete dual redundant MIL-STD-1553B RT Unit supporting all 13 mode codes for dual
redundant operation. The CT2542 is a pin-for-pin functional equivalent of the DDC BUS-65142/144 and
performs parallel data transfers with a DMA type handshake. Multiple error flag outputs and host access to
many of the RT Status Word bits are just some of the features that make this part ideal for many RT
applications. The unit has an operating range of -55°C to + 125°C. Aeroflex is a MIL-PRF-38534 Certified
Manufacturer. See "Ordering Information" (last sheet) for CT2543.
