74LVC1G18
1-of-2 non-inverting demultiplexer with 3-state deselected
output
Rev. 02 — 30 August 2007
Product data sheet
1. General description
The 74LVC1G18 is a 1-of-2 non-inverting demultiplexer with a 3-state output. The device
buffers the data on input pin A and passes it either to output 1Y or 2Y, depending on
whether the state of the select input (pin S) is LOW or HIGH. Input can be driven from
either 3.3 or 5 V devices. These features allow the use of these devices in a mixed
3.3 and 5 V environment.
This device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing the damaging backflow current through the device
when it is powered down.
2. Features

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For SC-74 and SC-88 packages: above 87.5
°C
the value of P
