Description
CT 2542 / CT2543 Dual Redundant Remote Terminal FOR MIL-STD-1553B
Manufacturer
Aeroflex Circuit Technology
Datasheet
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
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.
