Electrical Specifications
Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure
to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. Assumes maximum of 10 pF loads on all outputs in still air, and a thermal ground pad under the LQFP. For 15 pF loads on each
output, air circulation of TBD must be present.
3. From CLKIN to OUT1
External Components
The MK74ZD133 requires some inexpensive external components for proper operation.
Decoupling
capacitors of 0.01F should be connected on each VDDxx pin to ground, as close to the device as possible
(adjacent VDDs can be connected together). A series termination resistor of 33
must be used for each
clock output. See the discussion on page 5 for other external resistors required for proper I/O operation.
