The MC14015B dual 4–bit static shift register is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. It consists of two identical, independent 4–state serial–input/parallel–output registers. Each register has independent Clock and Reset inputs with a single serial Data input. The register states are type D master–slave flip–flops. Data is shifted from one stage to the next during the positive–going clock transition. Each register can be cleared when a high level is applied on the Reset line. These complementary MOS shift registers find primary use in buffer storage and serial–to–parallel conversion where low power dissipation and/or noise immunity is desired.

• Diode Protection on All Inputs

• Supply Voltage Range = 3.0 Vdc to 18 Vdc

• Logic Edge–Clocked Flip–Flop Design —

Logic state is retained indefinitely with clock level either high or low; information is transferred to the output only on the positive going edge of the clock pulse.

• Capable of Driving Two Low–power TTL Loads or One Low–power

Schottky TTL Load Over the Rated Temperature Range.
