SL74HC4015
Semiconductor
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 serialinput/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
• 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 V

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
