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 1/ Circuit function Access time 01 512 × 8-bit registered PROM 30 02 512 × 8-bit registered PROM 35 03 512 × 8-bit registered PROM 40 04 512 × 8-bit registered PROM 30 05 512 × 8-bit registered PROM 35 06 512 × 8-bit registered PROM 40 07 512 × 8-bit registered PROM 25

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

Outline letter Descriptive designator Terminals Package style L CDIP4-T24 or GDIP3-T24 24 Dual-in-line 3 CQCC1-N28 28 Square chip carrier

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.
