scope:

This specification covers the detail requirements for monolithic silicon, low-power Schottky, TTL, binary and decade counters. 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, and as specified herein.

The device type shall be as follows:

Device type Circuit 01 Presettable decade counter, cascadable 02 Presettable 4-bit binary counter, cascadable 03 Decade counter 04 4-bit binary counter

The 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) A F-1 (14-lead, ¼" × ¼"), flat package B F-3 (14-lead, 3/16" × ¼"), flat package C D-1 (14-lead, ¼" × ¾"), dual-in-line package D F-2 (l4-lead, ¼" × ⅜"), flat package 2 C-2 (20-terminal .350" × .350"), square chip carrier package
