Essential for embedded labs
Bought this for my university embedded systems course. It's much more robust than building the circuit on a breadboard from scratch. The signal integrity is good even at higher speeds.

Fast shipping, great product
Arrived quickly and well-packaged. The chip is genuine TI stock based on the markings. Successfully used it to bridge an Arduino Uno and a Raspberry Pi without any level shifting errors.

Reliable for industrial prototyping
We use these in our prototyping lab for connecting various PLCs and microcontrollers. The LVC logic family is fast and low power. No issues with overheating or signal dropouts during extended testing.

Solid build, clear labeling
Great little board for learning about bus transceivers. The pinout is clearly marked on the silkscreen, which saved me time checking the datasheet. Only giving 4 stars because the included headers were slightly bent, but easily fixed.

Good value for money
Does the job well. The board is compact and fits nicely into standard project enclosures. Would have liked a small LED indicator for power, but that's a minor complaint for the price point.

Perfect for 3.3V to 5V projects
This board works exactly as expected. I needed a reliable way to interface my 3.3V ESP32 with some 5V sensors, and this SN74LVC4245A module handled the bidirectional shifting flawlessly. The soldering quality is excellent.
Q: Is this board suitable for unidirectional shifting only, or does it support bidirectional data flow?
A: The SN74LVC4245A chip supports fully bidirectional data flow. You can control the direction using the DIR pin, allowing data to move from Port A to B or vice versa dynamically.
Q: Does this come with pre-soldered headers?
A: No, the board typically ships with unsoldered pin headers in a separate bag to prevent damage during shipping and to give you flexibility in choosing straight or right-angle headers.
Q: Is there a schematic available for this specific MCU-245 board layout?
A: Yes, a PDF schematic and pinout diagram are available in the 'Documents' section of the product page. It details the connections for OE, DIR, and all 8 data lines.
Q: Can I power this board directly from a USB 5V source?
A: Yes, you can power the VCCB side with 5V from USB. However, ensure VCCA is supplied with the appropriate lower voltage (e.g., 3.3V) if you are shifting down to that level. Do not exceed the maximum voltage ratings for each port.
Q: What is the maximum operating frequency for this transceiver?
A: According to the Texas Instruments datasheet for the SN74LVC4245A, the typical propagation delay allows for operation up to approximately 100 MHz depending on voltage and load conditions.
