Notes:
1. Typical limits are: V_DD = 5.0 V and T_A = 25 °C.
2. The TTL inputs could be HIGH or LOW.
3. The I_OL and I_OH specifications are valid only for the RXCLK.
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.
