The MC74AC157DR2 is a high-speed quad 2-input multiplexer designed to select four bits of data from two sources using common Select and Enable inputs. It features true (non-inverted) output and can also function as a function generator, capable of producing any four of the sixteen different functions of two variables with one variable common. The Enable input is active-low, ensuring that when it is high, all outputs are forced low regardless of other inputs. This device can source or sink up to 24 mA of current per output and is available in Pb-free packaging. It operates within a supply voltage range of 2.0V to 6.0V for AC devices and 4.5V to 5.5V for ACT devices, with a recommended operating temperature range of -40¬8C to 85¬8C. The MC74AC157DR2 is suitable for applications requiring reliable data routing and function generation in digital circuits.
