scope:

This specification covers the detail requirements for monolithic silicon, advanced low power Schottky TTL, decade counters. 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.

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 Synchronous 4-Bit Decade Counter (Asynchronous Clear) 02 Synchronous 4-Bit Decade Counter (Synchronous Clear) 03 Synchronous 4-Bit UP/DOWN Decade Counter 04 Synchronous 4-Bit Decade Counter with 3-State Outputs 05 Synchronous 4-Bit UP/DOWN Decade Counter with 3-State Outputs

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) E D-2 (16-lead, ¼" × ⅞"), dual-in-line package F F-5 (16-lead, ¼" × ⅜"), flat package 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
