2-bit bidirectional translator for SDA and SCL lines in I²C applications
Provides bidirectional voltage translation with no direction pin
High-impedance output SCL_A, SDA_A, SCL_B, SDA_B pins when OE = 0 V or V_CC = 0 V
Internal 10-kΩ pull-up resistor on all SDA and SCL pins are enabled based on respective V_CC voltage
1.08 V to 3.6 V on both A and B ports
V_CC Isolation feature: If either V_CC input is at GND, both ports are in the high-impedance state (excluding pull-ups)
No power-supply sequencing required: either V_CCA or V_CCB can be ramped first
Low I_off of 2.5 µA when either V_CCA or V_CCB = 0 V
OE input can be tied directly to V_CCA or controlled by GPIO
Latch-up performance exceeds 100 mA per JESD 78, class II
ESD Protection exceeds JESD 22
- 2500-V Human-body model (A114-B)
- 1500-V Charged-device model (C101)

The TCA9416 is a 2-bit bidirectional I²C and SMBus voltage-level translator with an output enable (OE) input and rising and falling edge accelerators. It is operational from 1.08 V to 3.6 V on both the A-side and B-side. This allows the device to interface between lower and higher logic signal levels at any of the typical 1.2-V, 1.8-V, 2.5-V, and 3.3-V supply rails.

The OE input pin is referenced to V_CCA, can be tied directly to V_CCA, but it is also 3.6-V 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 configurations, the TCA9416 is compatible with standard speeds where the frequency of SCL is 100 kHz (Standard-mode), 400 kHz (Fast-mode), or 1 MHz (Fast-mode Plus).

The TCA9416 features internal 10-kΩ pull-up resistors on SCL_A, SDA_A, SCL_B, and SDA_B. Additional external pull-up resistors can be added to the bus to reduce the total pull-up resistance and speed up rising edges.
