U74LVC1G18

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 Y0 (output) and Y1 (output) is in the high-impedance state.

When the select input S is high data passes from A (input) to Y1

(output) and Y0 (output) is in the high-impedance state. 

The U74LVC1G18 is designed for 1.65V to 5.5V operation and 

it can be driven from either 3.3V or 5.5V devices. Therefore, it can 

be 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 and 

prevents damaging current backflow through the device when it is 

powered down.
