8-Channel variable voltage MOSFET based Level Shifters

Background

The 8-Channel bi-directional logic level shifter is a small device that safely operates in stepping up higher voltage (upto 6V) signals to lower voltage signals (upto 1.2V) and vice versa.

Product and Technology Description

The board consists of Low Voltage(LV+, LV-) 2 pin header and High Voltage(HV+, HV-) 3 pin header to provide supply voltages. This breakout has 8 BSS138 FETs with 10K pull-ups and individual channel capable of giving variable voltages with maximum volatge of 50V, current of 220mA and the power consumption is 360mW. It works down to 1.8V on the low side making it suitable for low power, low current applications. This board consists of led's for each channel which lit up as supply voltage is provided indicating the board is working fine! As you plug-in for a particular channel that channel led goes off showing that channel is selected.

Comes with a fully assembled, and tested PCB with 8 full bidirectional converter lines as well as 2 pieces of 8-pin header, 2-pin header, 3-pin header so you can solder on to a breadboard or perfboard for ease.
