NOTES: A. The pulse generators have the following characteristics: ZO = 50 Ω, tr = 10 ± 5 ns, tf = 10 ± 5 ns, tpd1 = 500 ns, PRR ≤ 1 MHz,

tpd2 = 1 µs, PRR ≤ 500 kHz.

B. Strobe input pulse is applied to Strobe 1G when inputs 1A-1B are being tested, to Strobe S when inputs 1A-1B or 2A-2B are being

tested, and to Strobe 2G when inputs 2A-2B are being tested.

C. CL includes probe and jig capacitance.

D. All diodes are 1N916.
