Overview
The SN74LV4051AQDYYRQ1 is an automotive-grade, 8-channel CMOS analog multiplexer and demultiplexer manufactured by Texas Instruments. Designed for VCC operation between 1.65V and 5.5V, it supports mixed-mode voltage signals up to 5.5V peak in either direction. The device features a low on-state resistance of 75Ω at 4.5V and a bandwidth of 35MHz. It operates within an ambient temperature range of -40°C to +125°C and is housed in a compact 16-pin SOT-23-THIN (DYY) package measuring 4.2mm x 3.26mm.
Feature Summary
- Qualified for automotive applications with AEC-Q100 certification
- Supports bidirectional transmission of analog and digital signals
- Low crosstalk and high on-off output-voltage ratio
- Latch-up performance exceeds 100mA per JESD 78, class II
Applications
- Automotive infotainment systems
- Instrument cluster signal routing
- Telematics and eCall modules
Procurement Notes
Verify the specific ordering suffix 'DYY' confirms the SOT-23-THIN package type during procurement. Confirm that the 'Q1' suffix indicates AEC-Q100 qualification for automotive use. Ensure the supply voltage matches the 1.65V to 5.5V operational range required for proper functionality.
Selection Notes
Select this component when space-constrained automotive designs require an 8-channel analog switch. The SOT-23-THIN package is suitable for high-density PCB layouts. Ensure the application requires mixed-signal handling capabilities and operates within the specified -40°C to +125°C temperature range.
Part Context
This part belongs to the SN74LV4051A-Q1 family of analog multiplexers. It shares functional specifications with other variants like SN74LV4051ATPWRQ1 but differs in physical packaging. The DYY suffix specifically denotes the thin small-outline transistor package variant optimized for automotive spatial requirements.
Replacement Considerations
SN74LV4051ATPWRQ1 offers identical electrical characteristics in a TSSOP-16 package. SN74LV4051ATDWRQ1 provides the same function in a standard SOIC-16 package. Verify pin compatibility and thermal management requirements when substituting packages.
