General Description
This Schottky TTL eight-bit universal register features multiplexed inputs/outputs to achieve full eight bit data handling in a single 20-pin package. Two function-select inputs and two output-control inputs can be used to choose the modes of operation listed in the function table.

FEATUREs
■ Multiplexed inputs/outputs provide improved bit density
■ Four modes of operation:
    Hold (Store) Shift Left
    Shift Right Load Data
■ 3-STATE outputs drive bus lines directly
■ Can be cascaded for N-bit word lengths
■ Operates with outputs enabled or at high Z
■ Guaranteed shift (clock) frequency 50 MHz
■ Typical power dissipation 700 mW
