Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range availability. Confirm that the requested variant matches the required JEDEC compliance standards and ESD protection levels specified in the latest product data sheet revision before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring 16-bit parallel data buffering with three-state isolation capabilities. Ensure the application operates within the 1.2 V to 3.6 V supply voltage range and requires five-volt tolerant I/O characteristics. Consider the low-inductance package benefits for high-speed digital designs where minimizing ground bounce is critical for signal integrity.

Part Context

This device belongs to the LVCH (Low-Voltage CMOS High-Speed) logic family, designed for high-speed operations with low power consumption. It follows a multibyte flow-through standard pin-out architecture, facilitating easy integration into existing PCB layouts. The component is manufactured using advanced CMOS technology to ensure compatibility with modern low-voltage digital systems while maintaining robust performance across varying temperature conditions.

Replacement Considerations

The datasheet revision history indicates that the 74LVCH16541ADL part number was removed in version 4 of the document. Designers should verify current availability and consider alternative packages such as the TSSOP48 (SOT362-1) variant listed in the ordering information table for equivalent functionality.
