The TXB0604 is an 4-bit non-inverting auto-bidirectional translator that uses two separate configurable power-supply rails. This voltage translator/ line redriver can be used to remedy voltage domain mismatches in addition to signal boosting in long-cabling transmission applications.

The TXB0604 leverages a patented design to achieve high data throughput for memory-intensive interfaces like Quad-SPI between BMC and Flash devices without signal integrity losses associated with excessive output parasitic capacitance.

The A port is designed to track VCCA. VCCA accepts any supply voltage from 0.9V to 2V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 3.6V.

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