During loading, serial data flow is. Shift right is accomplished synchronously with the rising. Serial data for this mode is entered at the shift-right data. Clocking of the flip-flop is inhibited when both mode control. Order Number Package Number.
Devices also available in Tape and Reel. Physical Dimensions inches millimeters unless otherwise noted.
The register has four distinct modes of operation, namely: The data is loaded into the associated flip-flops and appear at the outputs after the positive transi- tion of the clock input. During loading, serial data flow is inhibited.
Serial data for this mode is entered at the shift-right data input. Clocking of the flip-flop is inhibited when both mode control inputs are LOW.
