آی سی PCA9306DP1 پکیج SOP8

Description:
The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.6 V (Vref(1)) and 1.8 V to 5.5 V (Vbias(ref)(2)).

The PCA9306 allows bidirectional voltage translations between 1.0 V and 5 V without the use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. 

Application:
I2C Translation systems

Features:
Vref: -0.5 ~ +6 V
Vbias: -0.5 ~ +6 V
V input voltage: -0.5 ~ +6 V
VI/O voltage on an input/output pin: -0.5 ~ +6 V
Ich channel current: 128 mA
IIK input clamping current: -50 mA
Tstg storage temperature: -65 +150 °C

Pin description:
1, GND: ground (0 V)
2, VREF1: low-voltage side reference supply voltage for SCL1 and SDA1
3, SCL1: serial clock, low-voltage side; connect to VREF1 through a pull-up resistor
4, SDA1: serial data, low-voltage side; connect to VREF1 through a pull-up resistor
5, SDA2: serial data, high-voltage side; connect to VREF2 through a pull-up resistor
6, SCL2: serial clock, high-voltage side; connect to VREF2 through a pull-up resistor
7, VREF2: high-voltage side reference supply voltage for SCL2 and SDA2
8, EN: switch enable input; connect to VREF2 and pull-up through a high resistor
