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, advanced Schottky TTL, octal transparent and octal D type latches (three state) microcircuits. Two product assurance classes and a choice of case outlines and 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, (see 6.3). 1.2 Part or Identifying Number (PIN).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: Device type Circuit 01 Octal transparent latch with active low enable 3-state outputs 02 Octal transparent latch with active low enable 3-state outputs 03 Octal D-type latch with 3-state inverted outputs 04 Octal D-type latch with 3-state outputs 1.2.2 Device class. The device class is the product assurance level as defined in MIL-PRF-38535. 1.2.3 Case outlines. The case outlines are as designated in MIL-STD-1835 and as follows: Outline letter Descriptive designator Terminals Package style R GDIP1-T20 or CDIP2-T20 20 Dual-in-line S GDFP2-F20 or CDFP3-F20 20 Flat pack 2 CQCC1-N20 20 Square leadless chip carrier X CQCC2-N20 20 Square leadless chip carrier Comments, suggestions, or questions on this document should be addressed to: Commander, Defense Supply Center Columbus, ATTN: DSCC-VAS, 3990 East Broad St., Columbus, OH 43216-5000, or emailed to bipolar dscc.dla.mil.
