MILITARY SPECIFICATION
MICROCIRCUITS, DIGITAL, SCHOTTKY TTL, 1024 BIT RANDOM ACCESS MEMORY (RAM), MONOLITHIC SILICON
Inactive for new design after 24 July 1995
This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product herein shall consist of this specification sheet and MIL-PRF 38535
1. SCOPE
1.1 Scope. This specification covers the detail requirements for monolithic silicon, Schottky TTL, static, 1024 bit random
access memory microcircuits. Two product assurance classes and a choice of case outlines/lead finishes are provided for
each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been
superseded by MIL-PRF-38535, (see 6.4).
1.2 Part or Identifying Number (PIN). The PIN is in accordance with MIL-PRF-38535, and as specified herein.
1.2.1 Device types. The device types are as follows:
