3-STATE 8-Bit Universal Shift/Storage Register
General Description
This Schottky TTL eight-bit universal register features mul-
tiplexed inputs/outputs to achieve full eight bit data han-
dling 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.
Synchronous parallel loading is accomplished by taking
both function-select lines, S0 and S1, HIGH. This places
the 3-STATE outputs in a high-impedance state, which per-
mits data that is applied on the input/output lines to be
clocked into the register. Reading out of the register can be
accomplished while the outputs are enabled in any mode.
A direct overriding input is provided to clear the register
whether the outputs are ENABLED or OFF.
