1.4 Device Information

The TXV010x devices are 6-bit and 8-bit, dual-supply fixed and direction controlled low-skew voltage translation devices. The devices can be used for buffering, redriving, voltage translation, and power up isolation on timing-margin sensitive interfaces, such as Reduced Gigabit Media Independent (RGMII) signals between MAC and PHY.

Ax pins and the control pins (DIR, OE) are referenced to VCCA logic levels, and Bx pins are referenced to VCCB logic levels. The devices can accept I/O voltages ranging from 1.65V to 3.6V.

There are two pinout options: TXV0106/TXV0106-Q1 (6- bit fixed-direction voltage translator) and TXV0108/TXV0108-Q1 (8-bit direction-configurable voltage translator).

DIR pin is only available for the 8-bit device, which can be compatible with the AXC8T , AVC8T, LXC8T and LVC8T devices depending on the application. A high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A when OE is set to low. When OE is set to high, both Ax and Bx pins are in the high-impedance state. See the respective data sheets for more information.
