Description

Features:

CATEGORY	SPECIFICATIONS
Product Name	CJMCU-9306 I2C/SMBus Voltage Level Translator Module
Core Chip	PCA9306
Type	Dual bidirectional I2C/SMBus level translator
Channels	2-channel (SCL and SDA lines)
VREF1 Range	1.2V – 3.3V
VREF2 Range	1.8V – 5.5V
Translation Range	1.2V to 5V bidirectional logic level conversion
Direction Control	Automatic (no direction pin required)
Enable Control (EN)	High = active (connected); Low = high-impedance (isolated)
Switch Type	Low RON pass transistor (low ON-state resistance)
Propagation Delay	Minimal due to low resistance switching
Isolation Feature	Can isolate buses using EN control
Bus Speed Support	Supports I2C/SMBus communication (e.g., 100kHz and 400kHz separation)
Functionality	Bidirectional voltage translation and bus isolation
Key Features	Automatic bidirectional level shifting
	No direction pin required
	Low ON resistance for fast switching
	Enable pin for control and isolation
	Compatible with I2C and SMBus protocols
Applications	I2C device interfacing
	Mixed-voltage communication systems
	Microcontroller to sensor interfacing
	Bus isolation and signal level conversion
	Embedded and IoT systems
