DESCRIPTION
—
Ground.
I/O
Serial data bus. Connect to V_CC through a pullup resistor.
I
Serial clock bus. Connect to V_CC through a pullup resistor.
Supply voltage of I²C registers, oscillator, and control logic. Connect
—
directly to V_CC of the external I²C master. Provides voltage-level
translation.
O
P-port output 2. Open-drain design structure.
Enable input. If set to low, it puts the TCA6507 in shutdown mode and
I
resets the internal registers and I²C/SMBus state machine to their default
states.
