8.3 Feature Description
Each of the 8 channels is controlled by its input (Dn), a direct clear (CLR), and clock (CLK) through a positive-
edge-triggered D-type flip-flops. Information at the data (D) input meeting the setup time requirements is
transferred to the output (Y) on the positive-going edge of the clock (CLK) pulse. When CLK is at either the high
or low level, the D-input has no effect at the output. When CLR is at low level, the D-input has no effect at the
output.
