SN74LVCC3245APWT

Translators, Level Shifters Overview

The SN74LVCC3245APWT is a voltage-level translator manufactured by Texas Instruments, designed for bidirectional data transfer between buses operating at different logic levels. It features eight channels within a single circuit configuration housed in a 24-TSSOP package. The device supports a VCCA supply range of 2.3 V to 3.6 V and a VCCB supply range of 3 V to 5.5 V. Key electrical parameters include tri-state non-inverting outputs, an operating temperature range from -40°C to +85°C, and compliance with RoHS3 standards.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between low-voltage (VCCA) and higher-voltage (VCCB) domains
• Features tri-state outputs to effectively isolate buses when disabled
• Supports asynchronous communication across mixed-voltage system architectures

Translators, Level Shifters Applications

• Interfacing memory modules with varying voltage requirements
• Connecting microcontrollers to peripheral devices operating at different logic levels
• Mixed-signal PCB designs requiring level shifting between digital components

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'PWT' corresponds to the 24-TSSOP package and reel/cut-tape availability as listed by distributors. Confirm that the VCCA and VCCB pin assignments align with the target schematic design. Ensure the component meets the required RoHS3 environmental specifications for the intended application region.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting is required between a 2.3–3.6 V domain and a 3–5.5 V domain. It is suitable for applications needing high channel density in a compact surface-mount package. Consider alternative packages like SOIC if board space allows for wider trace routing or different thermal constraints.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC3245A series of octal bus transceivers and voltage translators. It shares functional similarities with other LVCC family members but is distinguished by its specific dual-supply voltage capabilities and TSSOP packaging. It serves as a bridge for systems integrating legacy 5V components with modern low-voltage logic.
