Overview
The SN74LV4051ADYYR is an 8-channel CMOS analog multiplexer and demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V, supporting mixed-mode voltage operation on all ports. The device handles both analog and digital signals with amplitudes up to 5.5V (peak) in either direction. It features extremely low input current, high on-off output-voltage ratio, and low crosstalk between switches. The component includes individual switch controls and robust ESD protection exceeding JESD 22 standards. It is housed in a 16-pin SOT-23-THIN package.
Feature Summary
- Supports mixed-mode voltage operation across all ports
- Provides high on-off output-voltage ratio for signal integrity
- Features extremely low input current consumption
- Includes robust electrostatic discharge protection
Applications
- Telecommunications systems
- eCall automotive applications
- Infotainment modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm material type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required operating temperature range, as designations such as '.A' indicate extended temperature capabilities compared to standard versions.
Selection Notes
Select this component when space-constrained designs require an 8-channel analog switch in a compact SOT-23-THIN footprint. Verify that the system supply voltage falls within the 1.65V to 5.5V range. Consider thermal resistance metrics if operating at higher ambient temperatures or with significant load currents.
Part Context
This part belongs to the SN74LV4051A family of 8-channel analog multiplexers. The 'DYY' suffix specifically denotes the 16-pin SOT-23-THIN package configuration. Other variants in the series utilize different form factors such as SOIC, TSSOP, or VQFN, while maintaining identical electrical functionality and pinout compatibility.
Replacement Considerations
Direct replacements include other SN74LV4051A variants with different packages, such as SN74LV4051ADR (SOIC) or SN74LV4051APWR (TSSOP). Cross-package substitution requires verifying pin-to-pin compatibility and ensuring the alternative package fits the available PCB real estate.
