Notes: 1. Typical limits are: VDD = 5.0 V and TA = 25 °C.

2. The TTL inputs could be HIGH or LOW.

3. The IOL and IOH specifications are valid only for the BYTECLK.

4. These are absolute values with respect to device ground.

5. No more than one output should be tested at a time. Duration of the short circuit should not exceed one second.
