Product Introduction
A dual bidirectional I²C and SMBus voltage-level translator with an enable (EN) input, operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. Allows bidirectional voltage translations between 1.2 V and 5 V without a direction pin. The low ON-state resistance (RON) of the switch allows connections with minimal propagation delay. When EN is high, the translator switch is ON, enabling bidirectional data flow between ports; when EN is low, the switch is off, and a high-impedance state exists between ports. Can be used to isolate a 400-kHz bus from a 100-kHz bus by controlling the EN pin.
Features
- 2-Bit Bidirectional Translator for SDA and SCL Lines in Mixed-Mode I²C Applications
- I²C and SMBus Compatible
- Less Than 1.5-ns Maximum Propagation Delay to Accommodate Standard-Mode and Fast-Mode I²C Devices and Multiple Masters
- Allows Voltage-Level Translation Between:
- 1.2-V VREF1 and 1.8-V, 2.5-V, 3.3-V, or 5-V VREF2
- 1.8-V VREF1 and 2.5-V, 3.3-V, or 5-V VREF2
- 2.5-V VREF1 and 3.3-V or 5-V VREF2
- 3.3-V VREF1 and 5-V VREF2
- Provides Bidirectional Voltage Translation With No Direction Pin
- Low 3.5-Ω ON-State Resistance Between Input and Output Ports Provides Less Signal Distortion
- Open-Drain I²C I/O Ports (SCL1, SDA1, SCL2, and SDA2)
- 5-V Tolerant I²C I/O Ports to Support Mixed-Mode Signal Operation
- High-Impedance SCL1, SDA1, SCL2, and SDA2 Pins for EN = Low
- Lockup-Free Operation for Isolation When EN = Low
- Flow-Through Pinout for Ease of Printed-Circuit Board Trace Routing
