Package
The macrocircuits are packaged in hermetically sealed ceramic packages which are
conform to case outlines of MIL-STD-1835 (when defined):
68-PIN SQ.PGA UP PAE Outline
68-PIN Ceramic Quad Flat Pack CQFP
The precise case outlines are described on Figure 23 and Figure 24.
Electrical
Characteristics
Recommended Condition of
Use
Unless otherwise stated, all voltages are referenced to the reference terminal (see
Table 1).
Notes:
1. Test load, see Figure 5.
2. Capacitance is periodically sampled rather than 100% tested.
