The SL74HC4015 is a high-performance silicon-gate CMOS dual 4-bit shift register. 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.
This document describes the SL74HC4015, a high-performance silicon-gate CMOS device consisting of two identical independent 4-stage serial-input/parallel-output registers. Each register features independent Clock and Reset inputs along with a single serial Data input, allowing for flexible data shifting operations.
