INCH-POUND MIL-M-38510/315D 27 October 2003 SUPERSEDING MIL-M-38510/315C 17 JANUARY 1984 MILITARY SPECIFICATION MICROCIRCUITS, DIGITAL, LOW-POWER SCHOTTKY TTL, COUNTERS, MONOLITHIC SILICON Inactive for new design after 18 April 1997. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, (see 6.3). 1.2 Part or Identifying Number (PIN).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.
