Overview
The SN74LV4052ATDRQ1 is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, designed for automotive applications. It operates on a single supply voltage ranging from 1.65V to 5.5V and supports bidirectional signal transmission with amplitudes up to 5.5V peak. The device features two independent 4:1 switches controlled by common select inputs (A, B) and an enable input (INH). Key electrical parameters include a nominal bandwidth of approximately 50 MHz, off-isolation of about 45 dB, and latch-up performance exceeding 100 mA per JESD 78 Class II standards. It provides ESD protection of 2000V HBM and 1000V CDM, operating within a temperature range of -40°C to +125°C in a 16-VSSOP package.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards for high-temperature operation
- Bidirectional analog and digital signal switching capability across the full supply voltage range
- Low crosstalk between switches and high off-isolation for signal integrity
- Robust electrostatic discharge protection meeting stringent automotive environmental requirements
Applications
- Automotive infotainment systems requiring signal routing
- Telecommunications equipment for signal gating and isolation
- Programmable logic circuits in automotive control modules
- Modulation and demodulation circuits in vehicle communication interfaces
Procurement Notes
Verify that the ordering suffix 'Q1' confirms AEC-Q100 automotive qualification. Ensure the 'TDR' package code matches the required 16-VSSOP footprint and pin pitch for PCB layout. Confirm the temperature grade corresponds to the specified -40°C to +125°C operational range for your specific automotive environment before finalizing procurement.
Selection Notes
Select this component when automotive certification is mandatory for analog signal routing. Compare against non-automotive variants like the SN74LV4052ADBR if cost sensitivity outweighs the need for AEC-Q100 compliance. Consider the 1.65V minimum supply voltage for low-power automotive standby modes. Verify that the 50 MHz bandwidth meets the highest frequency signals in your application.
Part Context
This part belongs to the SN74LV4052A family of dual 4-channel analog multiplexers. The 'Q1' suffix specifically denotes automotive qualification, distinguishing it from standard commercial versions. It shares functional compatibility with other LV series devices but offers enhanced thermal and reliability specifications suitable for harsh automotive environments compared to general-purpose logic components.
Replacement Considerations
The SN74LV4052ADBR is a functionally similar commercial-grade alternative but lacks AEC-Q100 certification. For direct automotive replacements, verify availability of other Q1 suffix variants from Texas Instruments or equivalent automotive-certified parts from other manufacturers that match the 16-VSSOP package and electrical characteristics.
