MIL-M-38510-320 Microcircuits, Digital, Bipolar Low-Power Schottky Ttl. Counters, Cascadable, Monolithic SiliconThis 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 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 For this product, the requirements of MIL-M- 38510 have been superseded by MIL-PRF-38535, see 6.3.

TABLE III.  Group A inspection for device type 03 - Continued.

Terminal conditions (pins not designated may be high � 2.0 V, or low s 0.7 V, or open).

1/  Case X and 2 pins not referenced are NC.

2/  Apply 4.5 V pulse, then ground prior to taking measurements to set device in the desired state.

3/  Apply two pulses after R0 (reset) pulse.

4/  Apply one pulse after R0 (reset) pulse.

5/  IIL limits are as follows:

6/  IOS limits for circuit C are -30/-130 mA.

7/  Only a summary of attributes data is required.

8/  A = 2.5 V minimum, B = 0.4 V.

9/  Output voltages shall be either:

a.  H � 1.5 V

b.  L s 1.5 V

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

11/  When testing tPHL1  or tPLH1, the QA pin shall be connected to the input B pin.

12/  Momentary 3.0 V (min), then ground.  Maintain ground for measurement.
