scope:

This specification covers the detail requirements for monolithic silicon, bipolar, low-power Schottky TTL, flip-flops, bistable logic 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 complete part number shall be in accordance with NIL-M-38510.

Device type shall be as shown in the following:

Device type Circuit 01 Octal D flip-flop with clear, cascadable 02 Octal D flip-flop with transparent latch and 3-state outputs non-cascadable 03 Octal D flip-flop with three-state outputs, cascadable 04 Octal D flip-flop with enable, cascadable

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

The case outline shall be designated as follows:

Outline letter Case outline (see MIL-M-38510, appendix C) R D-8 (20-lead, ¼" × 1 1/16"), dual-in-line package S F-9 (20-lead, ¼" × ½"), flat package 2 C-2 (20 terminal, .350" × .350"), square chip carrier package
