Controllers Procurement Notes

Verify the ACLEX suffix indicates tape-and-reel packaging containing 3000 units per reel. Confirm the component meets RoHS 3 and halogen-free standards. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements for this specific package variant.

Controllers Selection Notes

Select this model when a small footprint is required for battery-operated devices. Verify that the host system supports either I2C or SPI protocols. Ensure the application requires a single UART channel with full-duplex operation and compatibility with standard 16C450 register sets.

Controllers Part Context

This component belongs to the PI7C9X1170 product line from Diodes Incorporated. It serves as a protocol converter between digital buses and serial interfaces. The device is designed for cost-efficient applications requiring low power consumption and high data throughput within a compact physical form factor.

Controllers Replacement Considerations

Direct substitutes include the PI7C9X1170CLE (tube) and PI7C9X1170ACLE (tube). Verify pinout and electrical specifications match before replacing the reel-packaged version with tube-packaged equivalents.
