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 outline/lead finish are provided for each type and are reflected in the complete part number.

The part number shall be in accordance with MIL-M-38510.

The device type shall be as shown in the following:

Device type Circuit 01 Decade counter 02 4-bit binary counter 03 Synchronous 4-bit decade counter (asynchronous clear) 04 Synchronous 4-bit binary counter (asynchronous clear) 05 Synchronous 4-bit up/down decade counter 06 Synchronous 4-bit up/down binary counter 07 Synchronous 4-bit up/down decade counter (with clear) 08 Synchronous 4-bit up/down binary counter (with clear) 09 Synchronous 4-bit up/down binary counter (with mode control) 10 Divide-by-twelve counter 11 Synchronous 4-bit decade counter (with synchronous clear) 12 Synchronous 4-bit binary counter (with synchronous clear) 13 Synchronous 4-bit decade counter (with mode control)

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 (14-lead, ¼" × ⅜"), flat package E D-2 (14-lead, ¼" × ⅞"), dual-in-line package F F-5 (16-lead, ¼" × ⅜"), flat package 2 C-2 (20 terminal, .350" × .350"), square chip carrier package
