DESCRIPTION/ORDERING INFORMATION (CONTINUED)
Absolute Maximum Ratings(1) PCA9557D Texas Instruments(TI) IC I/O EXPANDER I2C 8B 16SOIC
SN74LVC1GX04 CRYSTAL OSCILLATOR DRIVER SCES581B–JULY 2004–REVISED DECEMBER 2006 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 3). The additional buffered inverter improves the signal quality of the crystal oscillator output by making it rail to rail. PCA9557D Texas Instruments(TI) IC I/O EXPANDER I2C 8B 16SOIC 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 PCA9557D Texas Instruments(TI) IC I/O EXPANDER I2C 8B 16SOIC
