Four-channel bidirectional logic level converter designed for 2.8V and 1.8V devices. Key benefits - Safe bidirectional voltage translation across four independent channels, enabling communication between high logic voltages and low logic voltages. - Simultaneous 5V to 3.3V downgrading and 3.3V to 5V upgrading across channels, protecting devices while enabling full two-way signaling. - Small form factor for easy integration on boards, prototypes, and compact systems. - Simple, reliable operation that reduces risk of damage when interfacing mixed-voltage components. Compatibility and performance - Works with 2.8V and 1.8V devices. - Four independent channels provide flexible routing for multiple signals. - Bidirectional function supports safe level shifting between high and low logic voltages. Use scenarios - Connect a 5V microcontroller to 2.8V or 1.8V sensors or peripherals without risking damage from voltage mismatch. - Interface 3.3V logic devices with 5V logic devices by translating 5V signals down to 3.3V and 3.3V signals up to 5V. - Use in development and testing to bridge different voltage domains across multiple signals in a compact, 4-channel module.
