Texas Instruments TXB0606 Auto-Bidirectional Level Translators

Texas Instruments TXB0606 Auto-Bidirectional Level Translators are 6-bit non-inverting autobidirectional translator that uses two separate configurable power-supply rails. These translators can be used to remedy voltage-domain mismatches and to boost signals in long-cabling transmission applications. The TXB0606 translators leverage a patented design to achieve high data throughput for memory-intensive interfaces without signal integrity losses associated with excessive output parasitic capacitance. These auto-bidirectional translators support high-speed interfaces such as QSPI, OSPI, and eSPI. Typical applications include data center and enterprise computing, desktop PC, and personal electronics.
