4 Channel Bi-Directional Logic Level 3.3V-5V Shifter

The module performs bi-directionally transfer with 4 channels between high logic voltage and low logic voltage. That is, steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time.

Each logic level converter has the capability of converting 6 pins on the high side to 6 pins on the low side with two inputs and two outputs provided for each side.

Instruction:

• Take the high voltage (5V) and low voltage (3,3V) for example.
• 5V connects to HV pin;
• 3.3V connects to LV pin;
• Ground from the system connects to GND pin.
• Specifications:
• High Voltage: 5V
• Low Voltage: 3.3V
• GND for negative power
• 5V TTL RXI input, 3.3V TTL RXO output
• TXI input/output of 3.3 V TTL, TXO input/output 5 V TTL, TXI and TXO bilateral switching
