Logic Level Converter Logic Level conversion 3.3 V to 5 V TTL bidirectional transfers

features:

1, 2 channels of logic and high voltage low voltage logic two-way transformation
2, 2 channels of high voltage logic into a low voltage logic of one-way conversion
3, small module, 1.5 cm X 1.5 cm
4, module compatible with bread plate, can be used directly put on the bread board
Instructions: the high voltage of 5 V low voltage of 3.3 V, for example)
HV connect 5 v power supply
LV 3.3 V power supply
GND connect power anode, both the power of the Commons
5 v TTL RXI input, will be in 3.3 v TTL RXO output
