产品概述
These Schottky TTL eight-bit universal registers feature 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.
Synchronous parallel loading is accomplished by taking both function-select
lines, S0 and S1, high. This places the three-state outputs in a high-impedance
state, which permits 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.
