SN74LVC2T45YZPRB

Translators, Level Shifters Overview

The SN74LVC2T45YZPR is a dual-bit, noninverting bus transceiver featuring configurable voltage translation between two independent power-supply rails. It supports bidirectional data transfer across A and B ports with supply voltages ranging from 1.65V to 5.5V. The device utilizes a single DIR input referenced to VCCA to control transmission direction. It operates within an ambient temperature range of -40°C to +85°C and is housed in an 8-pin DSBGA package.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design supporting full 1.65V to 5.5V operation on both ports
• VCC isolation feature ensures high-impedance state if either supply is grounded
• Ioff circuitry enables partial-power-down mode by disabling outputs to prevent backflow current
• Glitch-free power supply sequencing allows supplies to be powered on or off in any order

Translators, Level Shifters Applications

• Personal electronic devices
• Industrial systems
• Enterprise equipment
• Telecommunications infrastructure

Translators, Level Shifters Procurement Notes

Verify the specific suffix YZPR corresponds to the Texas Instruments NanoFree DSBGA package configuration. Confirm that the ordering information matches the required pinout for the bottom-view orientation. Ensure compliance with RoHS standards and check for any recent product change notifications affecting availability or specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing asynchronous communication buses requiring low-voltage bidirectional translation. The device is suitable for connecting systems operating at different voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V. Consider the maximum data rates and propagation delays relative to the specific voltage translation scenario.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC2T45 family of dual-bit dual-supply bus transceivers. It shares functional characteristics with other variants in the series but differs in packaging. The YZPR suffix specifically denotes the compact DSBGA form factor designed for space-constrained surface-mount applications.

Translators, Level Shifters FAQ

How does the VCC isolation feature function?

If either VCCA or VCCB input is connected to ground, both ports automatically enter a high-impedance state, regardless of the status of the other supply.

What is the purpose of the Ioff feature?

The Ioff feature disables the output circuits during partial-power-down mode, preventing damaging current backflow through the device when it is powered down.
