LOGIC LEVEL CONVERTER TTL BIDIRECTIONAL 4 CHANNELS LEVEL SHIFTER 5V-3.3V PEGELWANDLER Easy-to-use level converter, it is fed by the two voltages to be converted, high voltage (5 V for example) for the 'HV' pin, low voltage (3.3 V for example) for 'LV', and the system ground to the 'GND' pin. Plate with minimum dimensions and that allows the compatibility of 3.3V devices with 5 V and vice versa. 4 channel conversion capability. Based on the BSS138 field effect transistor Can work with 2.8V and 1.8V devices Dimensions: 16.05x13.33mm2mm less than 3 grams level adapter plate Links of interest: Data sheet for analogous product: https://learn.sparkfun.com/tutorials/bi-directional-logic-level-converter-hookup-guide Main component data sheet: https://cdn.sparkfun.com/datasheets/BreakoutBoards/BSS.
