74LVC1G19GM,115

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC1G19GM,115 is a single 1-of-2 decoder/demultiplexer housed in an XSON6 package (SOT886). It operates on a supply voltage range of 1.65 V to 5.5 V with inputs tolerant up to 5.5 V. The device features Schmitt-trigger action for noise immunity and includes IOFF circuitry for partial power-down protection. Static characteristics specify low leakage currents and high noise margins across the operating temperature range of -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders FAQ

How does the device behave when the Enable input is HIGH?

When the Enable input is HIGH, both outputs 1Y and 2Y assume a HIGH state regardless of the Input A level.

What is the purpose of the IOFF circuitry?

The IOFF circuitry disables the outputs to prevent potentially damaging backflow current through the device when it is powered down.
