Test circuit

Test data is given in Table 9. The An and Bn pins may be exchanged.

All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz; ZO = 50 Ω.

Definitions test circuit:

CL = Load capacitance including jig and probe capacitance; CEN = Decoupling capacitance; Rpu = Pull-up

resistance; RL = Load resistance; S1/S2 = Test selection switch
