8-Bit Bidirectional Universal
Shift Register with Parallel I/O
High-Speed Silicon-Gate CMOS
The IN74AC299 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 IN74AC299 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, S
1
and S
2
, 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.
Outputs Directly Interface to CMOS, NMOS, and TTL
