scope:

This drawing describes device requirements for class B microcircuits in accordance with 1.2.1 of MIL-STD-883, "Provisions for the use of MIL-STD-883 in conjunction with compliant non-JAN devices".

The complete PIN shall be as shown in the following example:

The device type(s) shall identify the circuit function as follows:

Device type Generic number Circuit function Frequency 01 80C187-10 80-bit numeric processor extension 10 MHz 02 80C187-12 80-bit numeric processor extension 12 MHz 03 80C187-16 80-bit numeric processor extension 16 MHz

The case outline(s) shall be as designated in MIL-STD-1835, and as follows:

Outline letter Descriptive designator Terminals Package style Q GDIP1-T40 or CDIP2-T40 40 Dual-in-line package X See figure 1 68 Ceramic quad flat package

The lead finish shall be as specified in MIL-STD-883 (see 3.1 herein). Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
