Description
TECHNICAL DATA
IN74HC4015A
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
