SN74LVCR2245ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245ANSR is an octal bus transceiver with three-state outputs from the Texas Instruments Widebus family. It operates from a single 2.7 V to 3.6 V supply and features inputs that accept voltages up to 5.5 V, enabling level translation between different voltage domains. The device provides a maximum propagation delay of 8.5 ns at 3.3 V and exhibits typical output ground bounce (VOLP) of less than 0.8 V at VCC = 3.3 V and TA = 25°C. It is housed in a 20-SOIC package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous communication between data buses
• Accepts input voltages up to 5.5 V while operating on lower supplies
• Minimizes output ground bounce for signal integrity

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Voltage level translation between 3.3 V and 5 V systems
• Bidirectional data transfer in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the tape-and-reel packaging format required for your assembly process. Confirm the manufacturer is Texas Instruments to ensure compatibility with the Widebus family specifications. Check RoHS compliance status and moisture sensitivity level before integration into production lines.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer is required between logic families operating at different voltage levels. The 5.5 V tolerant inputs allow direct interfacing with legacy 5 V devices without additional level shifting circuitry. Ensure the system supply voltage remains within the 2.7 V to 3.6 V range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A series, designed for high-speed bidirectional data transmission. It serves as a bridge between low-voltage logic cores and higher-voltage peripheral interfaces, commonly used in portable electronics and industrial control applications requiring robust signal integrity.
