onsemi Signal Switches, Multiplexers, Decoders MC74LCX258DTG

The MC74LCX258DTG is a low-voltage CMOS quad 2-input multiplexer designed for operation within a supply voltage range of 2.3 to 3.6 V. It features 5 V-tolerant inputs and outputs, allowing safe interfacing with 5 V TTL logic. The device has high impedance TTL compatible inputs that minimize current loading, while its outputs can drive up to 24 mA. The multiplexer provides inverted output data from two selectable sources, with the ability to switch outputs to a high impedance state via the Output Enable (OE) input. It supports live insertion and withdrawal, ensuring flexibility in circuit design. The device exhibits near-zero static supply current in all logic states, significantly reducing power requirements. Additionally, it has robust ESD protection, with ratings exceeding 2000 V for the human body model. The MC74LCX258DTG is available in a TSSOP-16 package and is compliant with RoHS standards.
