Description

VEE

Power supply pin connection.

CLK-EN

Synchronizing clock enable.

When HIGH, clock outputs follow clock input. When LOW, Q

outputs are forced low, QB outputs are forced high.

LVTTL/LVCMOS interface levels.

50 kΩ internal pull-up resistor.

—

CLK-SEL

Clock select input. When HIGH, selects CLK1 input. When

LOW, selects CLK0 input.

LVTTL/LVCMOS interface levels.

50 kΩ internal pull-down resistor.

CLK-IN0

True part of differential clock input signal. 75 kΩ internal

pull-down resistor.

CLK-IN0B

Complementary part of differential clock input signal.

100 kΩ internal pull-up and pull-down resistors.
