Overview
The SN74LV4051ANSR is an 8-channel CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2V to 5.5V and features a maximum on-resistance of 75 Ohms. The device provides a bandwidth of 35MHz with a propagation delay of 7ns. Switching times are limited to 14ns for both turn-on and turn-off. It functions within a temperature range of -40°C to +85°C and is housed in a 16-SOIC package.
Feature Summary
- Supports bidirectional transmission of analog and digital signals up to 5.5V peak amplitude
- Provides low on-resistance for efficient signal routing across eight channels
- Features high electrical performance with 35MHz bandwidth and fast switching speeds
Applications
- Signal gating in analog-to-digital and digital-to-analog conversion systems
- Chopper stabilization circuits
- Modulation and demodulation applications such as modems
- General-purpose signal multiplexing and demultiplexing
Procurement Notes
Verify the specific suffix ANSR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC package dimensions align with the target PCB footprint. Ensure the commercial operating temperature range meets system requirements, as automotive variants carry different suffixes. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when an 8:1 analog switch configuration is required within standard logic voltage ranges. The 75 Ohm on-resistance suits general-purpose signal routing where minimal distortion is needed. Consider the 16-SOIC package for surface-mount designs requiring moderate pin density. Verify that the 35MHz bandwidth satisfies the highest frequency components of the input signals to prevent attenuation or phase shift issues in the application circuit.
Part Context
This device belongs to the SN74LV4051A family of analog switches. It shares functional similarities with other members like the SN74LV4051ADR but differs in packaging and reel specifications. The series is designed for low-voltage CMOS applications, offering compatibility with various logic families while maintaining low power consumption and high noise immunity compared to older technology nodes.
Replacement Considerations
The SN74LV4051ANSRG4 is a verified lead-free variant of this component. Designers may also consider the SN74LV4051APWR for TSSOP packaging alternatives if board space constraints differ. Always verify pinout compatibility and electrical parameter tolerances before substituting any cross-package versions.
