Overview
The SN74LV4052AQDYYRQ1 is an automotive-grade dual 4-channel CMOS analog multiplexer and demultiplexer designed for 1.0V to 5.5V VCC operation. It handles both analog and digital signals with amplitudes up to 5.5V (peak). The device features fast switching, low crosstalk, and extremely low input current. It is qualified under AEC-Q100 standards with a temperature grade of 1 (-40°C to +125°C) and includes ESD protection exceeding JESD 22 specifications (2000V HBM, 500V CDM). Packaged in a 16-pin SOT-23-THIN (DYY) format measuring 4.2mm x 3.26mm, it supports mixed-mode voltage operation on all ports.
Feature Summary
- Qualified for automotive applications meeting AEC-Q100 Grade 1 requirements
- Supports mixed-mode voltage operation on all ports
- Provides high on-off output-voltage ratio with low crosstalk between switches
- Features extremely low control input current and robust electrostatic discharge protection
Applications
- Automotive signal gating and isolation
- Signal chopping and modulation/demodulation
- Signal multiplexing for analog-to-digital and digital-to-analog conversion systems
Procurement Notes
Verify the specific ordering suffix 'RQ1' corresponds to the SOT-23-THIN package and tape-and-reel quantity of 3000 units. Confirm that the RoHS status is compliant and check the moisture sensitivity level rating prior to soldering. Ensure the supply voltage range aligns with the system's power rails to maintain optimal ON-state resistance performance.
Selection Notes
Select this component when automotive reliability and extended temperature ranges are required. The SOT-23-THIN package offers a compact footprint suitable for space-constrained designs. Verify that the signal amplitude does not exceed 5.5V peak and that the system can accommodate the propagation delay characteristics at the intended operating voltage.
Part Context
This part belongs to the SN74LV4052A-Q1 family of dual 4-channel analog multiplexers. It shares functional similarities with non-automotive variants like the SN74LV4052ADBR but differs in qualification standards and temperature ratings. The 'Q1' suffix denotes automotive qualification, while 'DYY' specifies the thin small-outline transistor package type used in this specific configuration.
Replacement Considerations
Direct replacements include other SN74LV4052A-Q1 variants with different packages such as SN74LV4052AQPWRQ1 (TSSOP) or SN74LV4052ATDRQ1 (SOIC), provided pin compatibility and thermal requirements are met. Non-automotive equivalents like the standard SN74LV4052A may be considered if automotive certification is not mandatory.
