The device provides an additional unbuffered inverter (OSCOUT) and a Schmitt-trigger input inverter for signal conditioning (see Figure 3). The control (CTRL) input disables the oscillator circuit to reduce power consumption.

SN74LVC1404 OSCILLATOR DRIVER FOR CRYSTAL OSCILLATOR OR CERAMIC RESONATOR www.ti.com SCES469D – AUGUST 2003 – REVISED JANUARY 2007 APPLICATION INFORMATION Figure 3 shows a typical application of the SN74LVC1404 in a Pierce oscillator circuit. The output voltage can be conditioned further by connecting OSCOUT to the Schmitt-trigger input inverter. The Schmitt-trigger input inverter produces a rail-to-rail voltage waveform. The recommended load for the crystal, shown in this example, is 16 pF.
