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 Frequency Circuit function 01 82C54 8 MHz CMOS monolithic programmable interval timer 02 82C54-12 12 MHz CMOS monolithic programmable interval timer
The case outline(s) shall be as designated in MIL-STD-1835 and as follows:
Outline letter Descriptive designator Terminals Package style J GDIP1-T24 24 Dual-in-line 3 CQCC1-N28 28 Square chip carrier package
The lead finish shall be as specified in MIL-II-38510. 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.
