Hi-Speed 8-Channel Logic Level Converter Module — 3.3V / 5V Bidirectional
A high-speed 8-channel bidirectional logic level converter for safely interfacing 3.3V and 5V devices. Converts all 8 channels simultaneously with an output enable (OE) pin for bus isolation. Supports SPI, UART, and general digital signals at high frequencies — ideal for high-speed SPI buses where MOSFET-based converters are too slow.
Key Specifications
- Channels: 8 bidirectional | Voltages: 3.3V ↔ 5V
- Output enable: OE pin (active HIGH)
- Max frequency: high-speed (suitable for SPI)
- Supply: 3.3V VCCA + 5V VCCB
- Compliance: RoHS compliant
Why Choose This?
- ✅ 8 channels — convert full SPI bus (MOSI/MISO/SCK/CS + 4 more) at once
- ✅ High-speed — suitable for fast SPI and digital signals
- ✅ OE pin — disable all outputs for bus sharing
- ✅ Bidirectional — signals pass in both directions simultaneously
Typical Applications
- High-speed SPI bus level conversion
- 8-channel GPIO level shifting between 3.3V and 5V
- Connecting 3.3V SD cards and flash to 5V Arduino
- Mixed-voltage digital bus interfacing
