TECHNICAL DATA

KK74AC299

8-Bit Bidirectional Universal

Shift Register with Parallel I/O

High-Speed Silicon-Gate CMOS

The KK74AC299 is identical in pinout to the LS/ALS299,

HC/HCT299. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LS/ALS outputs.

The KK74AC299 features a multiplexed parallel input/output data port

to achieve full 8-bit handling in a 20 pin package. Due to the large output

drive capability and the 3-state feature, this device is ideally suited for

interface with bus lines in a bus-oriented system.

Two Mode-Select inputs and two Output Enable inputs are used to

choose the mode of operation as listed in the Function Table.

Synchronous parallel loading is accomplished by taking both Mode-

Select lines, S₁and S₂, high. This places the outputs in the high-

impedance state, which permits data applied to the data port to be clocked

into the register. Reading out of the register can be accomplished when

the outputs are enabled. The active-low asynchronous Reset overrides all

other inputs.
