TXS0108E 8 CHANNEL LOGIC LEVEL CONVERTER

TXS0108E High-Speed Full-Duplex 8 Channel Logic Level Converter is a bi-directional voltage-level translator module designed for high-speed data transfer between systems operating at different logic levels. It supports voltage translation between 1.2V to 3.6V on the low-voltage side and 1.65V to 5.5V on the high-voltage side, making it ideal for interfacing 3.3V and 5V devices.

Key Features of TXS0108E:

• • 8 Independent Channels: Allows level shifting for 8 separate signals.
  • Bi-Directional Communication: Supports full-duplex voltage translation automatically.
  • High-Speed Operation: Up to 110 Mbps for push-pull applications.
  • Auto Direction Sensing: No need for a direction control pin.
  • Wide Voltage Compatibility: 1.2V–3.6V (LV1 side), 1.65V–5.5V (LV2 side).
