The I2C-TRN board is an 8-pin CMOS
device that translates voltage level. It
allows bidirectional voltage translation
between 1.2V and 5V, without the use of a
direction pin. The low ON-state resistance
of the switch allows connections to be
made with minimal propagation delay.

embedded systems that require voltage
translation between the master and slave.
This I2C-TRN designed ready for 5V to
3.3V translator. It allows 5V system to
communicate to 3.3V device without
having external 3.3V supply.
This board features innovations that set it
apart from other voltage-level translator
module. Innovations feature like on-board
pull-up resistors, power LED and 3.3 V
regulator, which make it ready for 5V to
3.3V translator.

module can be quickly connected directly
on to the breadboard. The board is small
and compact in size 0.70 x 0.57 inches.
The I2C-TRN is designed base on
PCA9306 IC. This dual bidirectional I
voltage-level translator, with an enable
(EN) input, is operational from 1.2-V to
3.3-V V
When EN is high, the translator switch is
ON, and the SCL1 and SDA1 I/O are
connected to the SCL2 and SDA2 I/O,
respectively, allowing bidirectional data
flow between ports. When EN is low, the
translator switch is off, and a high-
impedance state exists between ports.
