Overview
The SN74LV4052ATPWRQ1 is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, designed for automotive applications under AEC-Q100 standards. It operates on a single supply voltage ranging from 2V to 5.5V. The device features two independent 4:1 switches controlled by common select inputs and an enable pin. Key electrical parameters include a maximum on-resistance of 75 ohms, a propagation delay of 25 ns, and a turn-off time of 25 ns. It supports bidirectional signal transmission with amplitudes up to the supply voltage. The component functions within a temperature range of -40°C to +125°C and is housed in a 16-TSSOP package.
Feature Summary
- AEC-Q100 qualified for automotive reliability requirements
- Dual independent 4-to-1 analog switch configuration
- Bidirectional signal switching capability
- Low on-resistance for minimal signal loss
Applications
- Automotive infotainment systems
- Signal gating and isolation in vehicle electronics
- Programmable logic circuits
- Modulation and demodulation circuits
Procurement Notes
Verify the specific suffix TPWRQ1 confirms the TSSOP-16 package and automotive grade qualification. Ensure the order matches the exact REEL packaging format required for surface-mount assembly processes. Cross-reference the manufacturer part number against official Texas Instruments documentation to confirm current production status and RoHS compliance before finalizing procurement orders.
Selection Notes
Select this component when designing for automotive environments requiring high reliability and wide operating temperature ranges. Compare the 75-ohm on-resistance and 25-ns switching speed against system bandwidth requirements. Consider the 16-TSSOP footprint constraints during PCB layout. Verify that the 2V to 5.5V supply range aligns with the target application's power architecture.
Part Context
This part belongs to the SN74LV4052A family of dual analog multiplexers. The 'Q1' suffix denotes automotive qualification, while 'TPWR' indicates the TSSOP-16 package type. It serves as a robust alternative to mechanical relays or discrete switch solutions in complex automotive circuitry, offering solid-state switching with low power consumption and high durability.
Replacement Considerations
SN74LV4052ADBR offers similar functionality in an SSOP-16 package without explicit automotive qualification. SN74LV4052ATPWREP provides the same TSSOP-16 form factor but may lack the specific Q1 automotive certification. Verify pin compatibility and electrical specifications before substituting.
