This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product herein shall consist of this specification sheet and MIL-PRF 38535
1. SCOPE
1.1 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/lead finish are provided
for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have
been superseded by MIL-PRF-38535, (see 6.3).
1.2 Part or Identifying Number (PIN). The PIN should be in accordance with MIL-PRF-38535, and as specified
herein.
1.2.1 Device types. The device types should be as follows:
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)
1.2.2 Device class. The device class should be the product assurance level as defined in MIL-PRF-38535.
