The M74HC151YTTR CONDITIONING & INTERFACES is a chip manufactured by STMicroelectronics that consists of two four-to-one multiplexers. Each multiplexer can be used to select between four logic high or low outputs. It is a high-speed Si-gate CMOS device specifically designed for low-power applications. Additionally, this chip has two data selector/multiplexer circuits. It can be used as a data selector, a line decoder, or an address multiplexer. Furthermore, this component features 8-bit address and data selection inputs, as well as output enable and selection enable control pins. The M74HC151YTTR is also equipped with active low outputs.
