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 01 1825 High speed PWM controller 02 1825A High speed PWM controller 03 1825B High speed PWM controller

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

Outline letter Descriptive designator Terminals Package style E CDIP1-T16 or GDIP2-T16 16 Dual-in-line 2 CQCC1-N20 20 Square leadless chip carrier X CQCC2-N28B 28 Square leadless chip carrier with thermal pads

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.
