Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions
for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB.
ψJB and θJA values
are determined for a 4-layer board in still-air number, unless otherwise stated. The circuit is designed to meet the DC specifications shown in the
above table after thermal equilibrium has been established.
4. For single-ended applications, the maximum input voltage for CLK, /CLK is VCC+0.3V.
5. Common mode voltage is defined as VIH.
6. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
