MIL-M-38510-56 Microcircuits, Digital, Cmos, Counters/Dividers, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, CMOS, logic microcircuits. Two product assurance classes and a choice of case outlines, lead finishes, and radiation hardness assurance RHA are provided and are reflected in the complete Part or Identifying Number PIN. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535 see 6.3.

MIL-M-38510/56G

NOTES:

1.  All outputs shall be checked for proper operation as specified in table III.

2.  To step counter through its sequence, momentarily place SW2 in position 2, then with SW3 in the required logic position, toggle SW1 to increment counter.

3.  See figure 2 for logic diagram and functional waveform.

4.  Test requirements are considered met if:  (a) counter advances with SW3 is in positions 1 and 3; (b) all counter outputs are logic "L" with SW3 in position 2; and (c) all counter outputs are logic "H" with SW3 in position 4.

5.  Test requirements are considered met if, with SW3 in position 1, the counter advances to a full count during 5 clock periods with outputs achieving logic "H".  At this point, SW3 is changed to position 2 and

after 5 more clock periods, a full count shall be registered with outputs achieving logic "L".
