MIL-M-38510-61 Microcircuits, Digital, Ecl, Flip-Flops, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, ECL, logic gating 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3.

FMAX IS HIGHEST INPUT FREQUENCY AT WHICH DEVICE CEASES TO TOGGLE

GENERATOR CHARACTERISTICS                                                                          

NOTES:

    zOUT = 50ν

    tTHL = 2.0 ns (20%-80%)

    tTLH = 2.0 ns (20%-80%)

    tP (data) = 200 ns

    tP (clock) = 40 ns 

1.   Perform test in accordance with test table; each output is tested separately.

2.   All input and output cables are equal lengths of 50 ohm coaxial cables.  Wire length should be ≤ .250 

      (6.35 mm) from tp in to input pin and tp out to output pin.

3.   Outputs not under test connected to a 100 ohm resistor to ground.

4.   Note that observed pulse amplitude is attenuated by one half.

5.   Power supply configuration on MC1660 and MC1662's identical to D.U.T.
