Bidirectional 1.4–3.6 V to 1.65–5.5 V translator
The ET-A19 is built around the TI TXS0108E — 8-bit auto-direction translator, push-pull + open-drain, up to 60Mbps push-pull / 2Mbps open-drain.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- 5 V peripherals on 3.3 V boards
- SPI and UART translation
- Parallel buses
