Alternate Parts for PCA9534DBR
This table gives cross-reference parts and alternative options found for PCA9534DBR. 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 PCA9534DBR, 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.
PCA9534DBR Frequently Asked Questions (FAQ)
-
The PCA9534DBR can support I2C bus frequencies up to 400 kHz.
-
To configure the PCA9534DBR to operate in input mode, set the corresponding bit in the configuration register (register 0x06) to 1. This will configure the pin as an input.
-
The PCA9534DBR can sink or source up to 25 mA per pin.
-
The PCA9534DBR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
-
The internal pull-up resistors on the PCA9534DBR are used to pull up the I2C bus lines (SDA and SCL) to the supply voltage (VCC) when the device is not actively driving the bus.
