MIL-M-38510-325 Microcircuits, Digital, Bipolar, Low-Power, Schottky Ttl, Flip-Flops, Cascadable, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, bipolar, low-power Schottky TTL, flip-flops, bistable logic microcircuits. 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/3250

NOTES:

1. Clear input dominates regardless of the state of clock or 0 inputs.

2. All diodes are 1N3064 or equivalent.

3. Clear input pulse characteristics: Vgen = 3.0 ±0.2 V, tO � 6 ns, tI � 15 ns, tP(clear) = 20 ns minimum and

PRR � 1 MHz.

4. CL = 50 pF ±10% (including probe and jig capacitance).

5. RL = 2 kn ±5 percent.

6. Clock input pulse characteristics: tP(clock) � 20 ns, VGEN = 3.0 ±0.2 V, PRR � 1 MHz.
