The TXB0108RGYRG4 is a bi-directional translate logic device designed for interface communication between systems of different logic families and supply voltage levels. It is a member of the TXB family of logic level translators, manufactured by Texas Instruments, that is specifically designed for low voltage applications. The TXB0108 will reliably and accurately translate signals between two logic families or voltage levels without the need for external voltage translation devices.

The TXB0108RGYRG4 employs a very simple application field and working principle. It provides bidirectional, asynchronous level translation using an internal charge pump circuit to generate the logic levels, translating between two logic families. When the device is enabled, the signals are translated between 1.2V and 3.3V signals. For example, a low level on the source side will be converted to a valid high level on the destination side.

The TXB0108RGYRG4 has a wide voltage operating range of 1.2V to 5.5V, combined with its low propagation delay, making it suitable for general-purpose logic translation. It can be used for applications such as three-state logic drivers, quiescent current drivers, voltage-level shifters, and bus switch applications.

The TXB0108RGYRG4 uses an I/O isolation circuit to provide isolation and improve noise immunity. The I/O isolation circuitry isolates the drain output from the source input. This allows the device to be used in applications where signal ground levels need to be kept separate, or where the signal needs to be protected from interference. Additionally, the I/O isolation circuit safeguards signal integrity by preventing ground bounce and cross-talk.

The TXB0108RGYRG4 employs a simple operation and can be used in both synchronous and asynchronous applications. The device has an enable pin that provides control and can be used to avoid erroneous transitions. Additionally, The TXB0108RGYRG4 makes use of the MOSFET’s LSL (Leakage Supression Logic) feature, which provides fast and reliable switching.

In summary, the TXB0108RGYRG4 is a logic level translator ideal for level translation between two logic families or voltage levels. It has an I/O isolation circuit that provides isolation, and an enable pin that provides control. With its wide voltage operating range and low propagation delay, the TXB0108RGYRG4 is ideal for general-purpose logic translation applications, and can be used in both synchronous and asynchronous applications.
