TXS4555RUTR Integrated Circuits (ICs)

Logic - Translators, Level Shifters, such as the TXS4555RUTR, are important building blocks of semiconductor devices that enable signals of one domain, such as voltage levels, to be converted into signals of a different domain. As the industry pushes towards faster and higher performing systems, the need for such devices is increasing. The TXS4555RUTR is a single logic-level translator with fast switching from rail-to-rail. This article will look at the features and capabilities of the TXS4555RUTR, its application field, and the working principle of its operation.

Features of the TXS4555RUTR

The TXS4555RUTR is a CMOS logic-level translator capable of converting TTL logic to LVCMOS logic with a low active voltage level of 0.45V. It also uses an internal pull-up resistor to ensure proper operation on a "1" logic level. It has an active low enable pin that allows it to be disabled when a logic low level is applied. Moreover, the TXS4555RUTR is capable of operating at up to 40MHz in a single-ended input and has a 15pF load drive.

Application Fields of the TXS4555RUTR

The TXS4555RUTR is widely used in a range of applications, from automotive to portable consumer devices and server applications. Its high switching speed and low active voltage level make it suitable for a variety of mixed-signal systems. In automotive applications, the TXS4555RUTR is used to interface vehicle driver controls, such as switches and buttons, to onboard electronics, such as ECUs and ECU gateways. In portable consumer devices, such as mobile phones, the TXS4555RUTR is used to convert the TTL logic signals to the lower voltage levels needed in the device. In server applications, the device is used to interface server control signals to the system board and other peripherals.

Working Principle of the TXS4555RUTR

The TXS4555RUTR operates in two logic comparator modes. In "Rail-to-Rail mode," the output of the device is a logic combination of the inputs. That is, if both inputs are logic high, then the output is logic high; if one input is logic low, then the output is logic low. In "Window mode," the output of the device is the opposite of the inputs; that is, if both inputs are logic high, then the output is logic low; if one input is logic low, then the output is logic high.

In addition, the TXS4555RUTR has an internal pull-up resistor that enables it to switch from rail-to-rail quickly and efficiently. The pull-up resistor ensures that a logic low level is pulled up to a logic one level and a logic high level is pulled down to a logic zero level. This ensures that the device can switch between logic levels quickly and efficiently, making it suitable for a variety of applications.

The TXS4555RUTR is a versatile and powerful logic-level translator that is capable of converting TTL to LVCMOS logic quickly and efficiently. Its wide range of application fields, such as automotive, portable consumer devices, and server applications are testament to its versatility and robustness. The TXS4555RUTR is an excellent device for mixed-signal systems, and its rail-to-rail switching and low active voltage levels make it an ideal choice for many applications.
