SN74LV4051APWRE4

Overview

The SN74LV4051APWRE4 is an 8-channel CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2 V to 5.5 V, supporting signal amplitudes up to the full supply range. The device features a maximum on-resistance of 75 Ohms and a bandwidth of 35 MHz. Electrical performance includes a propagation delay of 7 ns, with maximum switch times of 28 ns for both turn-on and turn-off. It functions within a temperature range of -40°C to +105°C and is housed in a 16-TSSOP package.

Feature Summary

• Supports bidirectional transmission of analog and digital signals across eight independent channels.
• Provides low power consumption with a maximum supply current of 20 uA.
• Ensures signal integrity through channel-to-channel matching of on-resistance.

Applications

• Signal gating in analog-to-digital and digital-to-analog conversion systems
• Chopper stabilization circuits
• Modulation and demodulation applications such as modems

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's official documentation to confirm material composition or RoHS compliance status. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference the datasheet revision history for any recent design or assembly changes that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when an 8-channel analog switching solution is required within a 2 V to 5.5 V operating range. The 16-TSSOP package is suitable for surface-mount applications requiring compact board space. Consider the 75 Ohm on-resistance and 35 MHz bandwidth limits to ensure compatibility with the target signal frequencies and impedance requirements.

Part Context

This part belongs to the SN74LV4051A series of high-speed CMOS logic devices. The 'E4' suffix typically denotes specific environmental or material compliance attributes defined by Texas Instruments. It shares functional compatibility with other variants in the LV4051 family, differing primarily in packaging, temperature rating, or manufacturing lot specifications.
