MIL-M-38510-2 Microcircuits, Digital, Ttl, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, TTL, bistable logic microcircuits. Three product assurance classes and a choice of case outlines/lead finish 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/2G

NOTES:

1. Clear and preset inputs dominate regardless of the state of clock or D inputs.

2. All diodes are 1N3064, or equivalent.

3. Clear or preset input pulse characteristics: Vgen = 3 V, to ≤ 7 ns, tp (clear) = tp (preset) = 35 ns, and PRR =

1 MHz.

4. CL = 50 pF, minimum (including jig and probe capacitance).

5. RL = 390n ±5%.

6. When testing clear to output switching, preset input shall have a negative pulse. When testing preset to

output switching, clear input shall have a negative pulse (see table III).
