Frequently Asked Questions
What is the SN74BCT8245ADW and what does it do?
The SN74BCT8245ADW is an 8-bit bidirectional bus transceiver from Texas Instruments. It features 3-state outputs and independent direction control, allowing data to flow in either direction between two 8-bit buses. It is part of the BCT (BiCMOS) logic family and operates at 5V supply voltage.
What package does the SN74BCT8245ADW come in?
The SN74BCT8245ADW comes in a 20-pin SOIC (Small Outline Integrated Circuit) wide-body package, indicated by the 'DW' suffix. This surface-mount package is suitable for automated PCB assembly and offers a compact footprint for board-space-constrained designs.
What are typical applications for the SN74BCT8245ADW?
Typical applications include bus buffering in computer backplanes, memory interface circuits, industrial control systems, and embedded processor boards. The bidirectional capability with direction control pin makes it ideal for any design requiring isolated, driven data transfer between two 8-bit parallel buses.
What is the difference between SN74BCT8245ADW and standard 74245 transceivers?
The SN74BCT8245ADW uses Texas Instruments' BCT BiCMOS technology, which offers faster switching speeds and higher output drive current (24mA) compared to standard CMOS 74HC245 variants. The BCT family is optimized for driving large capacitive bus loads while maintaining compatibility with both TTL and CMOS logic levels.
