Notes: 1. AC measurements assume that tT = 1 ns.

2. The reference level for timing of input signals is 1.4 V.

The input signal conditions are below.

VIH = 2.4 V, VIL = 0.4 V

3. Output load.

Output

Z = 50Ω

50 pF (External Load)

4. The access time is defined at 1.4 V.

5. If tT is longer than 1 ns, then the reference level for timing of input signals is VIH and VIL.
