TCA9554ADWT | Texas Instruments | $0.6170 | 8-bit 1.65- to 5.5-V I2C/SMBus I/O expander with interrupt, weak pull-up & config registers 16-SOIC -40 to 85 | TCA9554ADWR vs TCA9554ADWT |
The TCA9554ADWR can support I2C bus frequencies up to 400 kHz.
To configure the TCA9554ADWR to operate in input mode, set the corresponding bit in the configuration register (Register 0x03) to 1. This will enable the input mode for the respective pin.
The TCA9554ADWR can sink or source up to 25 mA per pin.
The TCA9554ADWR 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 TCA9554ADWR are used to pull up the I2C bus lines (SCL and SDA) to the supply voltage (VCC) when the device is not actively driving the bus.
