SN74LVCR2245ADBQR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245ADBQR is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous communication between data buses. It features three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device provides a propagation delay of 7.5 ns and supports TTL/CMOS input levels with LVTTL output levels. It delivers a low-level output current of 12 mA and a high-level output current of -12 mA. The component functions in non-inverting mode and includes direction control. It is rated for operation from -40°C to +125°C and utilizes a 24-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBQR' corresponds to the 24-pin SSOP tape-and-reel packaging configuration. Confirm that the device meets RoHS compliance standards and lead-free manufacturing requirements as specified by Texas Instruments. Ensure the operating temperature range aligns with system thermal design constraints before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer is required between buses operating at compatible low-voltage logic levels. The LVCR series offers robust performance for general-purpose bus switching. Consider the 24-pin SSOP package dimensions for PCB layout compatibility. Verify that the 7.5 ns propagation delay meets the timing requirements of the target application interface.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of octal bus transceivers. It shares functional characteristics with variants such as SN74LVCR2245ADW and SN74LVCR2245ARGYR, differing primarily in package type and reel specifications. The LVCR series is engineered for low-voltage applications requiring reliable bus isolation and direction control.
