Overview
The SN74LV4052APWG4 is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, operating on a single supply voltage ranging from 1.65V to 5.5V. It integrates two independent 4:1 switches controlled by common select inputs (A and B) and an enable input (INH). The device supports bidirectional signal transmission for both digital and analog signals with amplitudes up to 5.5V peak. Key electrical parameters include a maximum on-resistance of 75 ohms, propagation delays of 25ns, and a bandwidth of approximately 50MHz. It features low off-isolation of 45dB and high ESD protection ratings of 2000V HBM and 1000V CDM. The component is housed in a 16-TSSOP package and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Dual independent 4:1 analog switching architecture with shared control logic
- Bidirectional signal path support for mixed analog and digital applications
- Low on-resistance and low crosstalk characteristics for signal integrity
- High electrostatic discharge protection exceeding standard JESD specifications
Applications
- Signal gating and isolation in telecommunications equipment
- Audio and video signal routing in consumer electronics
- Sensor signal multiplexing in industrial measurement systems
- Data acquisition channel selection in programmable logic circuits
Procurement Notes
Verify the specific suffix 'PWG4' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the ordering information matches the required tape-and-reel or cut-tape format. Cross-reference the date code and lot number with quality certificates if the application requires traceability. Confirm availability through authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a design requires two separate 4-to-1 analog switching paths within a single compact package. It is suitable for low-voltage systems operating down to 1.65V. Consider the 75-ohm on-resistance limit for signal loss calculations. Verify that the 50MHz bandwidth meets the highest frequency component of the analog signal being switched. Ensure the TSSOP-16 footprint fits the PCB layout constraints.
Part Context
This part belongs to the SN74LV4052A family of CMOS analog switches. It serves as a general-purpose solution for replacing mechanical relays or discrete switch arrays. The device is designed to interface with various logic families due to its wide supply voltage range. It complements other members of the LV series such as the SN74LV4051A and SN74LV4053A.
Replacement Considerations
Direct pin-compatible alternatives include the SN74LV4052ADBR and SN74LV4052ATPWREP. Verify functional equivalence regarding on-resistance and propagation delay before substitution. Check for any differences in packaging or environmental qualifications between the original and replacement parts.
