SN74LVCC3245APWR

Translators, Level Shifters Overview

The SN74LVCC3245APWR is an octal bus transceiver and voltage level shifter from Texas Instruments, designed for asynchronous communication between data buses. It operates with VCCA at 2.3 V to 3.6 V and VCCB at 3 V to 5.5 V. The device features eight bidirectional channels in a 24-pin TSSOP package. Control inputs reference the VCCA voltage, allowing seamless switching between 3.3-V and 5-V systems without board re-layout.

Translators, Level Shifters Feature Summary

• Supports bidirectional data transfer between A and B buses based on direction control logic levels.
• Enables voltage level shifting between low-voltage (2.3 V–3.6 V) and high-voltage (3 V–5.5 V) domains.
• Provides three-state outputs to effectively isolate buses when the output enable input is deactivated.

Translators, Level Shifters Applications

• Asynchronous communication between data buses
• Voltage level translation between 3.3-V and 5-V systems
• Bidirectional bus driving applications

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-24 package and reel packaging configuration. Confirm that the operating temperature range meets the -40°C to 85°C requirement. Ensure compatibility with the required VCCA and VCCB supply voltages before integration into the design.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families requiring distinct supply voltages for input and output sides. It serves as a direct replacement for standard 245 devices where voltage translation is necessary. Consider the 24-pin TSSOP footprint during PCB layout planning to ensure adequate clearance for the package dimensions.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC3245A series of octal bus transceivers. It shares functional similarities with the SN74LVC4245A but offers specific voltage ranges tailored for mixed-voltage environments. The device integrates control circuitry referenced to VCCA for simplified system management.

Translators, Level Shifters FAQ

How does the device handle voltage differences between ports?

The SN74LVCC3245APWR allows independent supply voltages for Port A (VCCA: 2.3 V to 3.6 V) and Port B (VCCB: 3 V to 5.5 V), enabling safe level shifting between these domains.

What determines the direction of data flow?

Data flows from A to B or B to A based on the logic level of the Direction (DIR) control input pin.
