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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.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 or preset inputs dominate regardless of the state of clock or J-K inputs.
2.	Clear or preset input pulse characteristics: Vgen = 3 V, t0 = t1 = 10 ns, tp(clear)	=
3.	tp(preset) = 30 ns, PRR = 1 MHz, and ZOUT � 50n. CL = 50 pF, minimum (CL includes probe and jig capacitance).
4.	RL = 390n ±5%.
5.	All diodes are 1N3064, or equivalent.

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

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