Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the VQFN-16 package dimensions against PCB footprint requirements. Ensure the operating voltage range aligns with system power rails. Check for moisture sensitivity level (MSL) handling instructions during assembly. Validate that the component meets environmental regulations applicable to the target market.

Selection Notes

Select this component when a dual-channel, low-voltage multiplexer is required for space-constrained designs. The VQFN-16 package offers a compact solution compared to larger SOIC or SSOP alternatives. Consider the 40 Ohm on-resistance limit for signal integrity requirements. This part is suitable for applications where low power consumption and high-speed performance are critical constraints.

Part Context

This component belongs to the SN74CBTLV3253 series of low-voltage FET multiplexers. It serves as a specialized switch IC designed for modern portable and battery-operated devices. The series provides high-density signal routing capabilities while maintaining low power consumption. It complements other logic families by offering superior speed and lower voltage operation than standard CMOS counterparts.

Replacement Considerations

SN74CBTLV3253DR: Same functional device in SOIC-16 package. SN74CBTLV3253RGYR: Same function in VQFN-16 package. SN74CBT3253DBR: Higher voltage variant (4.5V–5.5V) in SSOP-16 package.
