CT2512 Replaces DDC BUS-65112 and BUS-65117 CT2513 Replaces DDC BUS-65113 and BUS-65118 CT2510 Replaces DDC BUS-65110 and BUS-65120 CT2511 Replaces DDC BUS-65111 and BUS-65121 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 Approved DESC SMD# 5962–87535 General Description The CT2512 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 CT2512 is a pin-for-pin functional equivalent of the DDC BUS-65112/117 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 CT2513 / CT2510 / CT2511.
