CT 2542 / CT2543 Dual Redundant Remote Terminal FOR MIL-STD-1553B Features • CT2542 Replaces DDC BUS-65142 and BUS-65144 • CT2543 Replaces DDC BUS-65143 and BUS-65145 • Functions as a Complete Remote Terminal Unit • Supports 13 Mode Codes, Illegalization of Codes Allowed • Transfers Data with DMA Type Handshaking • Latched Outputs for Command Word and Word Count • 14 Bit Built-ln-Test Word Register • 4 Error Flag Outputs • Advanced Low Power VLSI Technology • DESC SMD# 5962–89798 Approved CIRCUIT TECHNOLOGY www.aeroflex.com A E RO F LE X LA B S C ISO 9001 E RTIFIED I NC . 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.
