TECHNICAL DATA
8-Bit Bidirectional Universal
Shift Register with Parallel I/O
High-Performance Silicon-Gate CMOS
KK74HC323A
The KK74HC323A is identical in pinout to the LS/ALS323. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
The KK74HC323A features a multiplexed parallel input/output data
port to active 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, S1 and 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 synchronous Reset overrides all
other inputs.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 µA
High Noise Immunity Characteristic of CMOS Devices
