Freescale Semiconductor

1. Simulation circuit for parameters Voh and Vol for I/O cells is below

2. Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.

3. Minimum condition: bcs model, OVDD = 3.6 V / 1.95 V and –40 °C. Typical condition: typical model, OVDD = 3.3 V / 1.8 V, and

25 °C. Maximum condition: wcs model, OVDD = 3.0 V, and 105 °C.

4. Typical condition: typical model, OVDD=3.3 V / 1.8 V, and 25 °C. Maximum condition: bcs model, OVDD=3.6 V / 1.95 V, and

105 °C.
