DFRobot Fermion: 4-Bit & 8-Bit Level Translators

DFRobot Fermion: 4-Bit and 8-Bit Level Translators are level conversion modules that feature strong level compatibility and fast signal conversion speed. These translators use two separate configurable power-supply rails. The A port is designed to track V_CCA, port B is designed to track V_CCB, and V_CCA must be less than or equal to V_CCB. These translators offer low power consumption, bidirectional automatic conversion, and no direct control are needed. This module can be used in the level conversion of communication protocols such as I²C, UART, SPI, and OneWire. The 4-Bit and 8-Bit level translators operate at -30°C to 75°C temperature range.

Features

Low power consumption
Bidirectional automatic conversion and no direction control are needed
