TCA9406DCTR

Специализированный интерфейс, I2C, I2C Шина и SMBus Системные Применения, 1.65 В, 3.6 В, SSOP.

The TCA9406DCTR is a 2-bit bidirectional 1MHz I?C Bus and SMBus Voltage-level Shifter with an output enable (OE) input. The OE input pin is referenced to VCCA, can be tied directly to VCCA, but it is also 5.5V tolerant. The OE pin can also be controlled and set to a logic low to place all the SCL and SDA pins in a high-impedance state, which significantly reduces the quiescent current consumption. Under normal I?C and SMBus operation or other open-drain configurations, the TCA9406 can support up to 2Mbps. Therefore, it is compatible with standard I?C speeds where the frequency of SCL is standard-mode and fast-mode or fast-mode plus. The device can also be used as a general purpose level translator and when the A and B-side ports are both driven with push-pull devices the TCA9406 can support up to 24Mbps.
