1. General description

The 74LVC1GX04 combines the functions of the 74LVC1GU04 and 74LVC1G04 to

provide a device optimized for use in crystal oscillator applications.

The integration of the two devices into the 74LVC1GX04 produces the benefits of a

compact footprint. It provides lower power dissipation and stable operation over a wide

frequency and temperature range.

Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this

device in a mixed 3.3 V 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.

74LVC1GX04 NXP Semiconductors X-tal driver To calculate the values of C1 and C2, the designer can use the formula: C1  C2 C L = ------------------- + C s C1 + C2 CL is the load capacitance as specified by the crystal manufacturer. Cs is the stray capacitance of the circuit (for the 74LVC1GX04 it is equal to an input capacitance of 5 pF). 74LVC1GU04 portion X1 74LVC1G04 portion X2 Y system load Rf Csys C2 Xtal Rsys C1 mnb103 Fig 10.
