Overview
The M74HC151YRM13TR is a high-speed CMOS 8-channel multiplexer manufactured by STMicroelectronics using silicon gate C2MOS technology. This device allows the selection of one bit of data from up to eight sources, making it versatile for various digital logic applications. It can also function as a universal function generator to produce any logic function of four variables. The multiplexer has complementary outputs Y and W, with the selection determined by the address inputs A, B, and C. The strobe input must be taken low to enable the device, and all inputs are protected against static discharge and transient excess voltage.
