TCA9416
Overview
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 Aside and B-side.
- 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 VCC = 0 V
- Internal 10-kΩ pull-up resistor on all SDA and SCL pins are enabled based on respective VCC voltage
- 1.08 V to 3.6 V on both A and B ports
- VCC Isolation feature: If either VCC input is at GND, both ports are in the high-impedance state (excluding pull-ups)
- No power-supply sequencing required: either VCCA or VCCB can be ramped first
- Low Ioff of 2.5 µA when either VCCA or VCCB = 0 V
- OE input can be tied directly to VCCA or controlled by GPIO
- Latch-up performance exceeds 100 mA per JESD 78, class II
