The HI-15530 is a high performance CMOS integrated circuit designed to meet the requirements of MIL-STD-1553 and similar Manchester II encoded, time division multiplexed serial data protocols. The HI-15530 contains both an Encoder and Decoder that operate independently. It is fully compatible with either 5V or 3.3V logic and transceivers.

The device generates MIL-STD-1553 sync pulses, parity bits as well as the Manchester II encoding of the data bits. The decoder recognizes and identifies sync pulses, decodes data bits, and performs parity checking.

The HI-15530 supports the 1Mbit/s data rate of MIL-STD-1553 over the full temperature and voltage range.

For applications requiring small footprints and low cost, the HI-15530 is available in a 24-pin plastic SOIC package. Ceramic DIP and LCC packages are also available to achieve the highest level of reliability and to provide drop-in replacement for obsolete parts from other manufacturers.
