MIL-M-38510-25 Microcircuits, Digital, Bipolar, Ttl, Low Power, Counters, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, Schottky TTL, binary and decade counters. Two product assurance classes and a choice of case outlines and lead finishes 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

TABLE III.  Group A inspection for device type 02 - Continued. Terminal conditions (pins not designated may be H � 2.0 V, L ≤ 0.8V, or open)

1/    Momentarily apply 2.0 V, then ground prior to taking measurements to set the device in desired state.  Maintain ground for measurement.

2/    Same as 1/, except apply one pulse after reset (R0) pulses.

3/    Same as 1/, except apply two pulses after reset (R0) pulses.

4/    Same as 1/, except apply four pulses after reset (R0) pulses.

5/    Output voltages shall be either:  (a)  H = 2.4 V, minimum and L = 0.3 V maximum when using a high speed checker double comparator; or

(b)  H � 1.5 V and L ≤ 1.5 V when using a high speed checker single comparator.

6/    Input voltages shown are:  A = 2.4 V; B = 0.3 V.

7/    Only a summary of attributes data is required.

8/    fMAX, minimum limit specified is the frequency of the input pulse.  The output frequency shall be one-half of the input frequency.
