10.3 AC ELECTRICAL CHARACTERISTICS
10.3.1
AC Test Conditions
FIGURE 10-1. AC Test Conditions, TA = 0 °C to 70 °C, VDD = 5.0 V ±10%
Notes:
1. CL = 100 pF, includes jig and scope capacitance.
2. S1 = Open for push-pull output pins.
S1 = VDD for high impedance to active low and active low to high impedance measurements.
S1 = GND for high impedance to active high and active high to high impedance measurements.
RL = 1.0KΩ for µP interface pins.
3. For the FDC open-drive interface pins, S1 = VDD and RL = 150Ω.
