SN74LVCR2245ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245ADGVR is an octal bus transceiver from the Texas Instruments LVCR series, 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 offers a low-level output current of 12 mA and a high-level output current of -12 mA. Packaged in a VQFN-20 format, it functions as a non-inverting bidirectional transceiver suitable for industrial temperature ranges from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the DGVR suffix indicates a VQFN-20 package. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating environment remains within the specified -40°C to +125°C temperature range. Validate that the 2 V to 3.6 V supply voltage constraints are met for reliable operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when asynchronous octal bus interfacing is required with low-voltage operation. The LVCR series is appropriate for applications needing mixed-mode signal handling and downward voltage translation. Consider the VQFN-20 package if space-constrained surface-mount assembly is necessary. Verify compatibility with TTL/CMOS inputs and LVTTL outputs for system integration.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of octal bus transceivers. It shares core electrical characteristics with variants like the APWR and ARGYR, differing primarily in packaging. The LVCR series focuses on low-voltage, high-speed data transfer with robust I/O capabilities for modern digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include SN74LVCR2245APWRE4 (TSSOP-20) and SN74LVCR2245ARGYR (VQFN-20). Verify pinout and package dimensions before substitution. Ensure the alternative variant maintains the same 7.5 ns propagation delay and 12 mA drive current specifications.
