The MC74LCX158MELG is a low-voltage CMOS quad 2-input multiplexer designed to operate within a supply voltage range of 2.3 to 3.6 V. It features 5 V-tolerant inputs, allowing it to interface with 5 V TTL logic, which enhances its versatility in mixed-voltage applications. The device provides high impedance TTL-compatible inputs that minimize current loading on input drivers, while its TTL-compatible outputs improve switching noise performance. This multiplexer can select between four bits of data from two sources using select and enable inputs, presenting the selected data in inverted form at the outputs. It has a current drive capability of 24 mA, making it suitable for driving loads directly. The device also boasts a low static supply current of 10 mA, which significantly reduces overall system power requirements. Additionally, it exceeds latchup performance specifications and offers robust ESD protection, with ratings of over 2000 V for the human body model and over 200 V for the machine model. The MC74LCX158MELG is available in an EIAJ SO-16 package, with options for different packaging configurations to suit various production needs.
