TECHNICAL DATA
KK74HC4015A
Dual 4-Bit Shift Register
High-Performance Silicon-Gate CMOS
The device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL outputs.
This device consists of two identical independent 4-stage serial-
input/parallel-output registers. Each register has independent Clock and
Reset inputs as well as a single serial Data input. “Q” outputs are
available from each of the four stages on both registers. All register stages
are D-type, master-slave flip-flops. The logic level present at the Data
input is transferred into the first register stage and shifted over one stage
at each positive-going clock transition. Resetting of all stages is
accomplished by a high level on the reset line.

Outputs Directly Interface to CMOS, NMOS, and TTL
•
Operating Voltage Range: 2.0 to 6.0 V
•

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, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
