SN74LVC2T45YZPR

Translators, Level Shifters Overview

The SN74LVC2T45YZPR is a dual-bit, dual-supply bus transceiver from the Texas Instruments LVC logic series. It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes a DSBGA-8 package. The device features a propagation delay of 17.7 ns and supports a maximum data rate of 420 Mbps when converting between 3.3 V and 5 V levels. It functions as a non-inverting buffer with three-state outputs and is designed for asynchronous communication between two buses.

Translators, Level Shifters Feature Summary

• Supports fully configurable dual-rail design allowing independent operation across the entire 1.65 V to 5.5 V power supply range
• Provides VCC isolation to ensure both ports enter a high-impedance state if either VCC input is grounded
• Enables partial power-down mode operation through Ioff circuitry to prevent backflow current damage during shutdown

Translators, Level Shifters Applications

• Personal electronics systems requiring low-voltage bidirectional translation
• Industrial control interfaces utilizing mixed voltage signaling
• Enterprise infrastructure connecting disparate logic families
• Telecommunications equipment managing asynchronous data buses

Translators, Level Shifters Procurement Notes

Verify the specific suffix YZPR corresponds to the DSBGA-8 package configuration required for your layout. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to ordering. Ensure that the selected component matches the exact pinout and electrical specifications defined in the official SN74LVC2T45 datasheet to avoid integration errors.

Translators, Level Shifters Selection Notes

Select this component when designing circuits that require bidirectional level shifting between different voltage domains such as 1.8 V, 2.5 V, 3.3 V, and 5 V. It is suitable for applications needing compact surface-mount solutions with minimal footprint constraints. Consider its low static power consumption and high ESD protection ratings for robust performance in sensitive digital environments.

Translators, Level Shifters Part Context

This device belongs to the SN74LVC2T45 family of dual-supply bus transceivers manufactured by Texas Instruments. It is part of the broader LVC logic series designed for low-voltage CMOS applications. The YZPR suffix specifically denotes the DSBGA-8 packaging variant, distinguishing it from other package options like DCU or DCTR within the same logical function family.
