描述 Description

The U74LVC1G18 is a 1-of-2 non-inverting demultiplexer with 3-state output. When the select input S is low data passes from A(input) to 1Y (output) and 2Y (output) is in the high-impedance state.When the select input S is high data passes from A (input) to 2Y(output) and 1Y (output) is in the high-impedance state.The U74LVC1G18 is designed for 1.65V to 5.5V operation andit can be driven from either 3.3V or 5.5V devices. Therefore, it canbe used in a mixed 3.3V and 5V environment.The U74LVC1G18 is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs andprevents damaging current backflow through the device when it is powered down.
