scope:

This specification covers the detail requirements for monolithic silicon, bipolar, Advanced Schottky TTL, binary counter microcircuits. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete Part or Identifying Number (PIN) (see 6.7).

The device types shall be as follows:

Device type Circuit 01 Synchronous 4-bit binary counter (asynchronous master reset) 02 Synchronous 4-bit binary counter (synchronous reset) 03 Synchronous 4-bit up/down binary counter (with mode control) 04 Synchronous 4-bit up/down binary counter (asynchronous master reset)

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

The case outline shall be designated as follows:

Letter Case outline (see MIL-M-38510, appendix C) E D-2 (16-lead, .840" × .310" × .200"), dual-in-line package F F-5 (16-lead, .440" × .285" × .085"), flat package X C-2A (20 terminal, .358" × .358" × .075"), square chip carrier package 2 C-2 (20 terminal, .358" × .358" × .100"), square chip carrier package
