Alternate Parts for PCA9538DGVR
This table gives cross-reference parts and alternative options found for PCA9538DGVR. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of PCA9538DGVR, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
PCA9538DGVR Frequently Asked Questions (FAQ)
-
The PCA9538DGVR can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
-
The PCA9538DGVR is configured to operate in 16-bit mode by default. To operate in 8-bit mode, the A0 and A1 pins must be tied to VCC or GND to select the desired mode.
-
Each GPIO pin can source or sink up to 25 mA of current, but the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
-
The PCA9538DGVR can be reset to its default state by applying a low pulse to the RESET pin or by performing a power-on reset (POR).
-
Yes, the PCA9538DGVR can be used as a level translator between 3.3V and 5V systems, but it is recommended to use external resistors to limit the current and voltage on the GPIO pins.
