SN74LVCR2245ARGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245ARGYR is an octal bus transceiver from the LVCR logic series, manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device provides low-level output current of 12 mA and high-level output current of -12 mA. It exhibits a propagation delay of 7.5 ns and accepts TTL/CMOS input levels while delivering LVTTL output levels. Housed in a VQFN-20 package, it supports surface mount installation and functions across a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Designed for asynchronous communication between data buses
• Provides non-inverting signal transmission with eight independent channels
• Supports mixed voltage domain interfacing through compatible input and output logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous data bus communication systems
• Mixed voltage domain interface circuits
• High-density memory module connections

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity against official Texas Instruments documentation before integration. Confirm that the VQFN-20 package matches your PCB footprint requirements. Ensure thermal management strategies align with the specified operating temperature range of -40°C to +125°C. Check moisture sensitivity handling procedures as indicated in the datasheet to prevent package damage during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust asynchronous bus arbitration with mixed voltage compatibility. The LVCR series offers specific electrical characteristics distinct from standard LVCH or LVC families. Verify that the 7.5 ns propagation delay meets your timing constraints. Consider the 12 mA drive capability for load requirements on connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of octal bus transceivers. It shares the VQFN-20 package form factor with other Texas Instruments logic devices like the SN74LVCH245ARGYRG4. Unlike the SN74LVC125ARGYR which is a quadruple buffer, this device handles eight bidirectional channels. It differs from the discontinued SN74CBTLV3245AZQNR by offering specific LVCR electrical performance metrics.
