Texas Instruments TXB0604 Auto-Bidirectional Level Translator

Texas Instruments TXB0604 Auto-Bidirectional Level Translator is a 4-bit non-inverting auto-bidirectional translator that uses two separate configurable power-supply rails. This voltage translator/line redriver can address voltage-domain mismatches and boost signals in long-cabling transmission applications.

The TXB0604 leverages a patented design to achieve high data throughput for memory-intensive interfaces, such as Quad-SPI, between BMC and Flash devices, without signal integrity losses caused by excessive output parasitic capacitance. The A port is designed to track VCCA and accepts a supply voltage of 0.9V to 2V. The B port is designed to track VCCB and accepts a supply voltage of 1.65V to 3.6V.

When the OE input is low, all outputs are placed in the high-impedance state. To ensure a high-impedance state during power-down or power-up, OE must be tied to GND via a pulldown resistor. The driver's current-sourcing capability determines the minimum value of the resistor. The Texas Instruments TXB0604 is designed so that the OE input circuit is supplied by VCCA.
