TECNOULAB 5pcs tca9548a 8 channel i2c IIc multichannel expansion card 1 to 8 tca9548
$27.99
- TCA9548TCA9548A 8-channel 1 to 8 TCA9548 8-way I2C IIC multi-channel expansion board
- CompatibleThe adapter is connected to an I2C device with multiple identical addresses on the same I2C port on the main control board for normal communication and use. Compatible with IIC bus and System Management Bus (SMBus), active low reset input, hot plug support, low standby current, no power-up failure, support for 1.8V, 2.5V bus-to-bus voltages V, 3.3V and 5V Level change.
- Compact DesignThere are 8 I2C interfaces on one expander and eight bidirectional transfer switches which can be controlled by the I2C bus. This means that after transferring 1 expansion, 8 identical addresses can be connected to the same I2C port. The device is also in normal use. The default address of this expander is 0x70, the address can be changed, and it can be set within 0x70~0x77 according to your needs.
- Description The switch has a power gate so that the VCC pin can be used to limit the maximum high voltage across the TCA9548A. Maximum high voltage limiting allows for different bus voltages to be used on each pair of channels so that 1.8V, 2.5V, or 3.3V components can communicate with 5V components without any additional protection
- High Performance In theory, 8 expanders can be cascade-connected at the address 0x70~0x77, and each expander can connect 8 devices with the same address. This realizes the same I2C port and connects 64 devices with the same address and uses them normally. Very powerful!
