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 Access time Refresh 01 256K × 1 DRAM 150 ns 256 cycles (4 ms) 02 256K × 1 DRAM 200 ns 256 cycles (4 ms) 03 256K × 1 DRAM 120 ns 256 cycles (4 ms)

The case outline(s) shall be as designated in appendix C of MIL-M-58510, and as follows:

Outline letter Case outline E D-2 (16-lead, .840" × .310" × .200"), dual-in-line package X See figure 1 (18-terminal, .305" × .505"), rectangular chip carrier package Y See figure 1 (18-terminal, .305" × .505"), rectangular chip carrier package
