SN74BCT2245DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT2245DWR is an octal bus transceiver manufactured by Texas Instruments, housed in a 20-SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a temperature range of 0°C to 70°C. The device features non-inverting bidirectional data transmission with three-state outputs. Key electrical specifications include a propagation delay of 7 ns, low-level output current of 64 mA, and high-level output current of -15 mA. Input and output levels are compatible with TTL logic standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates series damping resistors for signal integrity enhancement
• Provides non-inverting octal bidirectional data transmission
• Features three-state outputs for effective bus isolation

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus architectures requiring signal damping
• Bidirectional data transfer between microprocessors and memory modules
• Industrial control systems operating at standard TTL logic levels

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 0°C to 70°C commercial temperature rating aligns with the operational environment constraints. Ensure compatibility with existing PCB footprints designed for the 20-SOIC package type before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when integrating series damping resistors directly into the transceiver path is necessary to minimize signal reflections. It serves as a suitable alternative to the SN74ABT2245 or SN74F2245 families where internal damping is preferred over external discrete components. Verify that the 5V supply voltage requirement matches the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT2245 family of octal bus transceivers. It shares functional similarities with the SN74ABT2245 but utilizes BCT technology optimized for 5V operation. The inclusion of internal damping resistors distinguishes it from standard variants like the SN74HC245 or SN74F245, which require external termination networks.
