scope:

This specification covers the detail requirements for monolithic silicon, low-power Schottky, TTL, binary and decade counter microcircuits. Three product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the 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 Dual decade counter with A and B inputs 02 Dual 4-bit binary counter 03 Dual decade counter with clear and set-to-nine

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

The case outline shall be designated as follows:
