TECHNICAL DATA
Dual 4-Bit Shift Register
High-Performance Silicon-Gate CMOS
IN74HC4015
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
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
