Procurement Notes
Verify the specific suffix 'DFT2' corresponds to the 6-lead TSSOP package configuration during procurement. Confirm that the ordering part number matches the required tape and reel quantity if applicable. Ensure the device grade meets the environmental specifications for the intended application. Cross-reference the manufacturer's latest datasheet for any updates to pin assignments or electrical characteristics before finalizing the bill of materials.
Selection Notes
Select this component when a compact, low-power solution is needed for switching between two signal sources in low-voltage digital systems. The wide operating voltage range makes it suitable for interfaces involving mixed voltage domains. Consider the propagation delay and ON-resistance specifications if signal integrity is critical for high-speed data lines. The small form factor is advantageous for densely packed PCB layouts in mobile devices.
Part Context
This device belongs to onsemi's NLS series of low-voltage analog switches and multiplexers. It is designed to replace older, higher-voltage components in modern portable electronics. The series offers various configurations including single-pole double-throw (SPDT) and dual SPDT options. The NLAS4501 specifically addresses the need for minimal footprint and power consumption in battery-operated devices.
Replacement Considerations
Check for direct cross-reference part numbers from onsemi or other manufacturers offering compatible 2:1 muxes in TSSOP-6 packages. Verify that substitute parts match the 1.65V-3.6V operating range and have similar ESD protection levels. Ensure the replacement maintains the same pinout to avoid PCB redesign. Confirm availability of the specific DFT2 packaging variant.
