TPT29617A-VS1R

Dual channel level shift and repeater for SDA/SCL Lines in I²C Applications and SMBus Compatible Support multi-mode: Standard-mode (SM), Fast mode (FM), and Fast-mode Plus (FM+) Open-Drain I²C Input/Output Latching free operation Allows Voltage-Level Translation Between − VREF1 range 0.8 V to 5.5 V − VREF2 range 2.2 V to 5.5 V 5 V tolerant I²C -bus and enable pins High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW Support Low level output current up to 30 mA Latch-Up performance exceeds 600 mA ESD Protection: − 7000-V Human-Body Model 1500-V Charged-Device Model The TPT29617A device is a dual channel I²C level shift and repeater function with an enable (EN) input, and work from 0.8 V to 5.5 V VREF1 and 2.2 V to 5.5 V VREF2. The SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, will allow bidirectional data flow between ports. If EN is low, the translator switch is off, and a high-impedance state exists between ports to isolate both sides. Dual channel, bidirectional buffer isolates capacitance and allows 540 pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds. TPT29617A is available in SOP8 and MSOP8 package, and is characterized from -40°C to +125°C.
