Asychronous Operation
When used asychronously (SEL = 1), IN is a synchronous
enable and CLK is the input signal. With IN = 1, CLK
passes directly and continuously to all output pins. With
IN = 0, all outputs will transition to a logical 0 (Q = low,
Q* = high) after the next falling edge of CLK. The outputs
will remain low until after a falling edge of CLK while IN =
1. IN is designed to allow signals to be enabled and dis-
abled synchronously, with no glitches or runt pulses at
the output during enable / disable transition time.
The following truth table summarizes the 15XX and 19XX
operation.

Default Conditions
It is good practice to tie all unused inputs to a known,
stable, and a valid voltage level. However, several sig-
nals have internal pull up or pull down resistors and
therefore, have a known state when left floating. The
following chart summarizes the default conditions on the
15XX and 19XX inputs.
