IK Semicon IN74HC323A 8-bit bidirectional universal shift register with parallel i/o high-performance silicon-gate cmo Datasheet

TECHNICAL DATA
IN74HC323A
8-Bit Bidirectional Universal
Shift Register with Parallel I/O
High-Performance Silicon-Gate CMOS
The IN74HC323A 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 IN74HC323A 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 ModeSelect lines, S1 and S2, high. This places the outputs in the highimpedance 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

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open. I/O pins must be connected to a properly terminated line or bus.
