The MC74HC157ADG is a quad 2-input data selector/multiplexer designed for high-performance applications. It features a pinout compatible with the LS157 and can interface directly with CMOS, NMOS, and TTL logic levels. The device operates within a voltage range of 2.0 to 6.0 V and has a low input current of 1.0 µA, making it suitable for low-power applications. This multiplexer routes two nibbles (A or B) to a single output port (Y) based on the select input, providing non-inverted output. It can drive up to 10 LSTTL loads and includes an output enable feature that sets all outputs to low when activated. The device is compliant with JEDEC standard No. 7A and is AEC-Q100 qualified, making it suitable for automotive applications. Additionally, it is Pb-free, halogen-free, and RoHS compliant, ensuring it meets environmental standards. The MC74HC157ADG is available in a SOIC-16 package, with options for tape and reel packaging for efficient handling in production environments. Its characteristics make it a reliable choice for engineers looking for a versatile multiplexer in their designs.
