Description

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.
