MIL-M-38510-21 Microcircuits, Digital, Bipolar, Ttl, Low Power, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic, silicon, TTL, low power, 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/21F

NOTES:

1/ Clock input pulse has the following characteristics: Vgen = 3.0 V ±0.2 V, t0 = 15 ns, t1 = 15 ns, tP = 200 ns, PRR = 0.5 MHz, when testing fMAX, PRR = see table III.

2/ D input (pulse G and pulse H) has the following characteristics: Vgen = 3.0 V ±0.2 V, t0 = 15 ns, t1 = 15 ns, tSETUP = 50 ns, , tP = 100 ns and PRR is 50% of the clock PRR.

3/ All diodes are 1N916 or equivalent.

4/ CL = 50 pF minimum and includes probe and jig capacitance.

5/ RL = 4 kn ±5%.
