Product User’s Manual – LC04A

1. INTRODUCTION AND OVERVIEW

LC04A is a logic converter which help user to steps down 5V signals to 3.3V and steps up

3.3V to 5V with high speed. This converter also works with 2.8V and 1.8V devices. Each

level converter has the capability of converting 4 pins on the high side to 4 pins on the low

side. 4 channels for each site.

Another good feature is this converter is Breadboard friendly! Can be used with normal

serial, I2C, SPI, and any other digital signal. Does not work with an analog signal. The

level converter is very easy to use. The board needs to be powered from the two voltages

sources (high voltage and low voltage) that your system is using. High voltage (5V for

example) to the 'HV' pin, low voltage (2.8V for example) to 'LV', and ground from the

system to the 'GND' pin.

Features:

● 2 ways (bi-directional), logic zero will wins (dominant)

● LV must be lower voltage than HV

● LV can be as low as 1.8V, HV can go up to 5V.

● 4 channels, you can have TX, RX, CTS and RTS.

● UART, SPI, I2C, or simple sensor input that have different voltage level.

● Not analog converter nor amplifier.

● Dimension: 15mm x 16mm
