MIL-M-38510-371 Microcircuits, Digital, Bipolar, Advanced, Low-Power Schottky Ttl, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, advanced, low-power Schottky TTL, flip flops, bistable logic microcircuits. Two 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

MIL-M-38510/371B

NOTES:

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

2. Clear or preset input pulse charactersistics: tp ( clear ) = 15 ns; tp ( preset ) = 15 ns;

and PRR ≤ 1 MHz; t0 = 6 ±1.5 ns.

3. CL = 50 pF ±10% (including jug and probe capacitance without package in test fixture).

4. RL = 499ν ±1%.

5. When testing clear to output switching, preset input shall have a logical "1" voltage

applied. When testing preset to output switching, clear input shall have a logical

"1" voltage applied (see table III).

6. Voltage measurements are to be made with respect to network ground terminal.
