scope:

This specification covers the detail requirements for monolithic silicon,Schottky TTL, low power, 4-by-4 register file microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number.

The part number shall be in accordance with MIL-M-38510.

The device types shall be as follows:

Device type Circuit 01 4-by-4 register file with 3-state outputs, cascadable 02 4-by-4 register file with open-collector outputs cascadable

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outlines shall be designated as follows:

Letter Case outline (see MIL-M-38510, appendix C) E D-2 (16-lead, ¼" × ⅞"), dual-in-line package F F-5 (16-lead, ¼" × ⅜"), flat package 2 C-2 (20-terminal, .350" × .350"), square chip carrier package
