Procurement Notes

Verify the specific suffix OE against the manufacturer's official documentation to confirm the exact enable/disable configuration and tolerance specifications. Ensure that the required operating temperature range aligns with the component's rated limits before finalizing procurement orders. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability of the Mercury Electronics product.

Selection Notes

Select this component when a 1.8V supply voltage and LVCMOS logic levels are required for the target circuit design. The choice is appropriate for space-constrained applications due to the small 2.0x1.6mm footprint. Consider the enable/disable functionality if dynamic power management is a priority for the system architecture. Validate that the 10.48576 MHz frequency meets the specific clocking requirements of the downstream components.
