Holt provides a number of alternate source solutions for Data Device Corporation (DDC®) MIL-STD-1553 Terminals and Transceivers. All devices are direct drop-in replacements with register-level software compatibility and API support for the terminal devices. 

Holt also offers enhanced devices (HI-62003 and HI-62023) which are fully software compatible but include additional features such as Error-Correcting Code (ECC) SRAM. These devices, which come in compact 80-pin plastic packages (QFN and PQFP) offer a significant space and cost saving over the older traditional multi-chip module approach.
