Description

The TCA9406DCUR is a 2-bit bidirectional I²C and SMBus Voltage-level Translator with an output enable (OE) input. It is operational from 1.65 to 3.6V on the A-side, referenced to VCCA and from 2.3 to 5.5V on the B-side, referenced to VCCB. This allows the device to interface between lower and higher logic signal levels at any of the typical 1.8, 2.5, 3.3 and 5V supply rails. 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 I²C and SMBus operation or other open-drain configurations, the TCA9406 can support up to 2Mbps; therefore, it is compatible with standard I²C speeds where the frequency of SCL is 100kHz (Standard-mode), 400kHz (Fast-mode) or 1MHz (Fast-mode Plus).
2-bit Bidirectional translator for SDA and SCL lines in I²C applications
Provides bidirectional voltage translation with no direction pin
Internal 10kR pull-up resistor on All SDA and SCL pins
No power-supply sequencing required
OE Input can be tied directly to VCCA or controlled by GPIO
Latch-up performance exceeds 100mA per JESD 78, class II
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
