The Pascall P1200 Series of Data Bus Transformers is designed to satisfy the
requirements of MIL-STD-1553A / B (Def. Stan. 00-18 (Part 2) / 1) and may be
used in either the bus coupling or isolation configurations.
The Transformers are compatible with currently available transceivers and
integrated terminals, meeting all the electrical requirements of Manchester II serial
bi-phase data transmission including MACAIR specifications. They are also
designed to meet the requirements of MIL-T-21038 Grades 5&7 / Class S / Life X.
