Logic-translators, level shifters, or logic-level shifters specifications provide the ability for two or more ICs to operate at different logic voltage levels. The SN74LVC1T45YZPR is a 3-V to 1.8- V translation from Texas Instruments, designed to be used as a level translator in applications ranging from consumer electronics to cellular phones and devices. It can also be used as a voltage level shifter in control applications. This device is designed for use in electrically noisy environments and noise-immune logic level shifting is provided.

The SN74LVC1T45YZPR Logic Level Shifter is a dual-channel level translator, with one fixed level-shifter tailored for consumer electronics and other applications.The level shifter is designed to provide a flexibility of signal paths while helping to bridge different voltage domains. Depending on the application, it helps to improve signal integrity, along with maintaining high-performance levels. The device supports both digital and analogue voltage domains which helps in the comparison between the two in applications such as the control or conditioning.

The SN74LVC1T45YZPR is designed to function as a bidirectional translator: VCCA is the active logic supply voltage, VCCB is the passive logic supply voltage. When VCCA is greater than VCCB, the device is operating in the high-voltage direction, translating signals from the low voltage (VCCB) to the high voltage (VCCA). Conversely, when VCCB is greater than VCCA, the device is operating in the low-voltage direction, translating signals from the high voltage (VCCA) to the low voltage (VCCB).

The SN74LVC1T45YZPR is also designed for noise immunity. The logic levels for the device are determined by the state of the inputs on each side. The outputs are valid as long as the inputs are not within the noise window of 50-150 mV of slew rate and propagation delays. Any noise within this window will not be propagated through the device, reducing any possible chance of data errors or data losses.

The SN74LVC1T45YZPR is able to work with low-current applications due to an active-low enable pin which can be pulled low or high, depending on the application. When pulled low, the device shuts off, reducing current consumption. This is useful in applications such as power reduction in portable equipment and energy-saving applications.

The SN74LVC1T45YZPR is a popular device used in a variety of applications such as consumer electronics, automotive and medical, and industrial applications. Its wide variability of logic levels and noise immunity makes it ideal for applications which require a high degree of resilience in mixed-voltage environments. Furthermore, its low current consumption helps in applications where battery power is important. This device is a versatile and practical solution for a wide range of applications.
