3 Description

The TXB0606 is an 6-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 TXB0606 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 TXB0606 device is designed so the OE input circuit is supplied by VCCA.

This device is fully specified for partial power-down applications using I OFF. The I OFF circuitry disables the outputs, which prevents damaging current backflow through the device when the device is powered down.
