8 channels logic high voltage and low voltage logic two-way transformation, realize the Ax and Bx bidirectional transfers.

Conversion level range: 1.8 V to 6 V

Module size: 28 mm X 27.5 mm

Instructions: (to 3.3 V, 5 V to each other)

VCCA 3.3 V power supply

VCCB connect 5 v power supply

GND connect power cathode, two power supply

Ax input 3.3 V TTL level, Bx will output 5 V TTL level

Bx type 5 V TTL level, Ax the output 3.3 V TTL level
