Alternate Parts for PCA9554DB
This table gives cross-reference parts and alternative options found for PCA9554DB. 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 PCA9554DB, 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.
PCA9554DB Frequently Asked Questions (FAQ)
-
The PCA9554DB can support I2C bus frequencies up to 400 kHz.
-
The PCA9554DB can be reset by pulling the RESET pin low for a minimum of 1 ms. This will reset the device to its default state.
-
The PCA9554DB can sink or source up to 25 mA of current on each GPIO pin.
-
Yes, the PCA9554DB can be used as a level translator. It can translate signals from 1.8 V to 5 V or vice versa.
-
The PCA9554DB can be configured for input or output mode by writing to the configuration register (register 0x06). A '1' in the register sets the pin as an input, while a '0' sets it as an output.
