3 Description

The SN74LVC1GX04 device is designed for 1.65-V to

5.5-V VCC operation. This device incorporates the

SN74LVC1GU04 (inverter with unbuffered output)

and the SN74LVC1G04 (inverter) functions into a

single device. The LVC1GX04 is optimized for use in

crystal oscillator applications.

X1 and X2 can be connected to a crystal or resonator

in oscillator applications. The device provides an

additional buffered inverter (Y) for signal conditioning

(see Figure 5). The additional buffered inverter improves the signal quality of the crystal oscillator

output by making it rail to rail.

NanoStar and NanoFree package technology is a

major breakthrough in IC packaging concepts, using

the die as the package.

This device is fully specified for partial-power-down

applications using Ioff (Y output only). The Ioff circuitry

disables the outputs, preventing damaging current

backflow through the device when it is powered down.
