Logic translators and level shifters are devices used to convert a digital signal from one logic family to another, while preserving the integrity of the data. This can be done when two or more different logic families are used in the same circuit, or when a logic family needs to be adapted to its external environment. One such very useful and popular device is the SN74LVC1T45DRLR.

The SN74LVC1T45DRLR is a bidirectional, low voltage, high speed translator. It can be used as a translator between VCCIO pins of 1.65 to 5.5Volts, allowing the interface between low voltage and high voltage integrated circuits in the same system. It contains four bidirectional buffers, with Schmitt triggers on the inputs, allowing for the buffered transfer of single ended signals between two different logic families.

The output buffers contain bus hold logic which maintains the prior data state if the inputs are changed and the clock is disabled. This buffered data hold circuit is enabled when VCC-IO is greater than 15% of VCC3V3. The input and output pins of the SN74LVC1T45DRLR can tolerate and operate on input levels of up to 5.5 Volts. It has an output enable on the OEN pin, which when activated, allows the output to hold their state.

This device is targeted towards applications that require low power, low voltage operation and which require interfacing between multiple voltage bearers and families. It is useful in applications that require setting up and taking down complex signals, such as address, data and control buses, between low-voltage logic and high-voltage logic families.

The SN74LVC1T45DRLR is truly a versatile device. It is used for interfacing logic ranging from 3.3V logic to 5V logic and can also interface with multiple types of logic families, including TTL, CMOS, and asynchronous SRAM. It provides very fast and efficient level shifting with minimal power requirements and without any external components. With its small size, wide range of operating voltages, and low power consumption, it is ideal for use in system designs that use multiple logic families and/or multiple voltage levels.

The device can be used in a variety of applications, including communications and network devices, industrial and automotive data acquisition systems, computer, and digital signal processor applications. It can also be used for voltage translation between different logic families and for logic level conversion between different logic voltage levels.

The SN74LVC1T45DRLR is a feature-rich device that allows designers to connect two logic families at two different voltage levels. It offers fast level shifting with minimal power requirements, operates over a wide range of voltages, and accepts input levels up to 5.5 Volts. With its small size, wide range of operating voltages, and low power consumption, it is a great device for interfacing between low voltage and high voltage logic families.
