SN74LVC1GX04DCKT

The SN74LVC1GX04DCKT is a Crystal Oscillator Driver designed for 1.65 to 5.5V VCC operation. It 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. The additional buffered inverter improves the signal quality of the crystal oscillator output by making it rail to rail. 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.
