HD74HC299
8-bit Universal Shift/Storage Register (with 3-state outputs)
Description
The HD74HC299 features multiplexed inputs/outputs to achieve full 8-bit data handling in a single 20-pin package.
Due to the large output drive capability and 3-state feature, this device is ideally suited for interfacing with bus lines in
a bus oriented system. Two function select inputs and two output control inputs are used to choose the mode of
operation as listed in the function table. Synchronous parallel loading is accomplished by taking both function select
lines S
input/output lines to be clocked into the register. Reading out of the register can be done while the outputs are enabled
in any mode. A direct overriding clear input is provided to clear the register whether the outputs are enabled or
disabled.
