74CBTLV3245 Functional Block Diagram
Description
The 74CBTLV3245 octal bus switch has standard 245 pinouts and is designed for asynchronous communication between data buses. When the Output Enable (OE) is low, the 8-bit bus switch is on and Port A is connected to Port B. When OE is high, the switch is off and a high impedance exists between Port A and Port B. The 74CBTLV3245 operates at -40°C to +85°C.

EK-RA8M1, using SCI1 as a slave in simple SPI mode
We have tried to use SCI1. Regardless of the position of J61, we did not succeed.During the analysis, we found that the documentation of the EK-RA8M1 does not match the schematic.According to the schematic, J61 must be opened to activate Ethernet B.According to the description, J61 ...
