Dual 4-Bit Static Shift Register
Key Features
• 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 goingedge of the clock pulse.
• Capable of Driving Two Low-power TTL Loads or One Low-power Schottky TTL Load Over the Rated Temperature Range.
• Pb-Free Packages are Available*
Description
AI
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.
