Notes: 1. The pulse generator has the following characteristics:
PRR = 1 MH Z, 50 % duty cycle, t r = tf = 6.0 ns.
2. CL includes probe and jig capacitance.
3. 75 Ω connected between the pin and GND at t ZHD tHZD test.
180 Ω connected between the pin and GND at t ZHD tHZD test.
4. At tHZR, tLZR test, S1 and S2 are closed.
At tZHR test, S1 is open and S2 is closed.
At tZLR test, S1 is closed and S 2 is open.
