8.1 Overview

The TXV0106-Q1 is an 6-bit translating transceiver that uses two individually configurable power-supply rails. The device is operational with both VCCA and VCCB supplies as low as 1.65 V and as high as 3.6 V. Additionally, the device can be operated with VCCA = VCCB. The Ax port is designed to track VCCA, and the Bx port is designed to track VCCB.

The TXV0106-Q1 device is designed for asynchronous communication between data buses, and transmits data in a fixed direction from the A bus to the B bus. The output-enable input (OE) is used to disable the outputs so the buses are effectively isolated. The output-enable pin (OE) of the TXV0106-Q1 is referenced to VCCA. To enable the high-impedance state of the level shifter I/Os during power up or power down, the OE pin should be tied to VCCA through a pullup resistor.

This device is fully specified for partial-power-down applications using the Ioff current. The Ioff protection circuitry prevents excessive current from being drawn from or sourced into an input, output, or I/O while the device is powered down.

The VCC isolation or VCC disconnect feature is designed so that if either VCC is less than 100 mV or disconnected with the complementary supply within the recommended operating conditions, both I/O ports are weakly pulled-down and then set to the high-impedance state by disabling their outputs while the supply current is maintained. The Ioff-float circuitry prevents excessive current from being drawn from or sourced into an input, output, or I/O while the supply is floating.
