Overview
The SN74LV4051ATDWRQ1 is an automotive-grade CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It features a single 8-to-1 circuit configuration housed in a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 2V to 5.5V, supporting both analog and digital signal transmission with amplitudes up to 5.5V peak. Key electrical specifications include a maximum on-resistance of 75 ohms, a channel-to-channel matching of 1.3 ohms, and a -3dB bandwidth of 35MHz. Switching times are limited to 14ns for both turn-on and turn-off. It is certified under AEC-Q100 standards and functions within a temperature range of -40°C to 105°C.
Feature Summary
- AEC-Q100 qualified for automotive reliability requirements
- Supports bidirectional transmission of analog and digital signals
- Low on-resistance with tight channel-to-channel matching
Applications
- Signal gating in analog-to-digital and digital-to-analog conversion systems
- Chopper stabilization circuits
- Modulation and demodulation in modem applications
- General-purpose signal multiplexing
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and qualification status. Ensure the component meets the required AEC-Q100 grade for automotive integration. Cross-reference the EDA model availability for design simulation. Confirm RoHS3 compliance and moisture sensitivity level prior to assembly planning.
Selection Notes
Select this component when an 8-channel analog switch with automotive certification is required. Compare the 75-ohm on-resistance and 35MHz bandwidth against system signal integrity needs. Consider the 16-SOIC package dimensions for PCB layout constraints. Evaluate the -40°C to 105°C operating range against environmental conditions.
Part Context
This part belongs to the SN74LV4051A family of general-purpose analog multiplexers. The 'Q1' suffix denotes automotive qualification, distinguishing it from standard commercial variants like the SN74LV4051APWR or SN74LV4051ANSR. It shares core functional specifications with the broader LV4051 series but adheres to stricter automotive reliability standards.
Replacement Considerations
The SN74LV4051ATPWRQ1 serves as a pin-compatible alternative in a 16-TSSOP package. For non-automotive applications, the SN74LV4051APWR or SN74LV4051ANSR may be considered if AEC-Q100 certification is not mandatory.
