MIL-M-38510-13 Microcircuits, Digital, Bipolar, Ttl, Counters Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.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 03 - Continued.

Terminal conditions 21

11   Normal clock pulse:   (VIL < 0.8 V,  VIH > 2.0 V).

21   Terminal conditions (pins not designated may be H > 2.0 V, or L < 0.8 V, or open).

31   Output voltages shall be either:

(a)   H = 2.4 volts minimum and L = 0.4 volt maximum when using a high speed checker double comparator, or

(b)   H > 1.5 volts and L < 1.5 volts when using a high speed checker single comparator. (c)   X = Don't care.

41   Only a summary of attributes data is required.

51   A > 2.0 V, B < 0.8 V.  Input voltages shown are the maximum for VIL and the minimum for VIH.

61   FMAX, minimum limit specified is the frequency of the input pulse.  The output frequency shall be one-half of the input frequency.

71   Apply 1 clock pulse prior to input pulses.

81   Apply momentary GND, then 4.5 volts prior to input pulses, maintain 4.5 volts during test.

91   Minimum limit for circuit C shall be -0.5 mA.
