6 / 12 page www.lansdale.com Page 6 of 12 Issue 0 LANSDALE Semiconductor, Inc. ML12509, ML12511, ML12513 Figure 5. AC Test Circuit – All Pulse Generators are EH 137 or equiv. Pulse Generator #4 Pulse Generators 1, 2 and 4: PRF = 10 MHz PW = 50% Duty Cycle t + = t – = 2.0 ± 0.2 ns Pulse Generator 3: PRF = 2.0 MHz PW = 50% Duty Cycle t + = t – = 5.0 ± 0.5 ns All resistors are +1%. All input and output cables to the scope are equal lengths of 50 Ω coaxial cable. The 1950 Ω resistor at Pin 7 and the scope termination impedance constitute a 40 :1 attenuator probe. CT = 15 pF = total parasitic capacitance which includes probe, wiring, and load capacitance. Unused output connected to a 50 Ω resistor to ground.

Test outputs of the device must be tested by sequencing through the truth table. All input, power supply and ground voltages must be maintained between tests. The clock input is the waveform shown. 2. In addition to meeting the output levels specified, the device must divide by 5 or 8 during this test. The clock input is the waveform shown. 3. In addition to meeting the output levels specified, the device must divide by 6 or 9 during this test. The clock input is the waveform shown. Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained. Outputs are terminated through a 50 Ω resistor to –2.0 V. Test procedures are shown for only one gate. The other gates are tested in the same manner. VIHmax VILmin Clock Input |
