Pin Descriptions for 56 pin SSOP (F package)
Type: I = Input, O = output, P = power supply connection, I/O=input upon power up, becoming an output
clock within 10 ms later.
Important Note for OE functionality: To use the output enable function, once the OE has been taken
low, and the outputs have been tri-stated, the VDD must be removed and reapplied for the clocks to run
again.
Staggered output skews for 56 pin SSOP (F) To aid in the reduction of EMI, and to allow the board
designer the flexibility of running different length traces whose clock edges will still line up at their
destinations, the MK74ZD133F comes with different fixed skews for different outputs. All skews are with
respect to OUT1 (pin 1), and are measured into 33
termination resistors with 15 pF capacitive loads.
