SN74LVCR2245ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245ADW is an octal bus transceiver from the Texas Instruments LVCR logic series, designed for asynchronous communication between data buses. It features eight non-inverting channels with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 3.6 V and supports TTL/CMOS input levels while providing LVTTL output levels. Key electrical specifications include a propagation delay of 7.5 ns, maximum power supply current of 10 uA, and output drive capabilities of 12 mA low-level and -12 mA high-level currents. It functions reliably across an extended temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two independent 8-bit buses using a single direction control input.
• Features three-state outputs that effectively isolate the bus when the output enable signal is deactivated.
• Accepts input signals compatible with both TTL and CMOS logic families for versatile system integration.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between microprocessors and memory modules.
• Data routing and buffering in industrial control systems.
• Signal translation between different voltage domains in mixed-signal environments.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel versus tube packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm the moisture sensitivity level and storage conditions prior to soldering to prevent damage during reflow processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal width is required for bus architectures rather than hex or quad configurations. The LVCR series offers lower voltage operation compared to standard 5V logic, making it suitable for modern low-power designs. Verify that the 7.5 ns propagation delay meets the timing constraints of your specific clock frequencies.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of bus transceivers manufactured by Texas Instruments. The 'DW' suffix specifically denotes the 20-lead Small Outline Integrated Circuit (SOIC) package variant. This family is engineered to provide efficient data movement in complex digital systems requiring wide bus widths.
