Overview
The MC14094BDR2G, produced by onsemi, is an integrated circuit that combines an 8-stage shift register with a data latch for each stage and features three-state outputs. This device is designed to handle serial-to-parallel data conversion efficiently. Data is shifted on the positive clock transition, and the QS output data is available for high-speed cascaded systems, while the Q'S output data is shifted on the following negative clock transition for low-speed cascaded systems. The data from each stage of the shift register is latched on the negative transition of the strobe input, and the outputs are controlled by three-state buffers that can be placed in a high-impedance state by a logic Low on the Output Enable input.
