Overview
The SN74LV4051APWR 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, with a maximum power supply of 5.5V. The device features a 1x8:1 configuration housed in a 16-TSSOP surface-mount package. Key electrical parameters include a maximum on-resistance of 75 Ohms and a bandwidth of 35 MHz. Propagation delay is specified at 7 ns, while switch times (Ton/Toff) reach up to 28 ns. It supports an operating temperature range from -40°C to +105°C and draws a maximum supply current of 20 uA.
Feature Summary
- Supports bidirectional transmission of both analog and digital signals within the supply voltage range.
- Provides low on-resistance for efficient signal routing across multiple channels.
- Features high-speed switching capabilities suitable for data acquisition systems.
Applications
- Signal gating in analog-to-digital and digital-to-analog conversion systems.
- Chopping and modulation/demodulation circuits in communication equipment.
- Data acquisition systems requiring multi-channel signal selection.
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel orientation when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets, as environmental declarations may vary by production batch. Ensure the component meets the required military or automotive qualification standards if applicable, noting that standard commercial versions differ from qualified variants.
Selection Notes
Select this component when an 8-channel analog switch is required with a wide supply voltage range down to 2V. Compare propagation delay and on-resistance against other LV series devices if higher speed or lower impedance is needed. Verify that the 16-TSSOP package dimensions fit the PCB layout constraints. Consider thermal dissipation requirements given the operating temperature range and potential load currents.
Part Context
This part belongs to the SN74LV4051A family of low-voltage CMOS analog switches. It shares functional similarities with other members like the SN74LV4051APW but differs in packaging and reel specifications. The LV series is designed for applications requiring compatibility with low-voltage logic families while handling analog signals efficiently.
Replacement Considerations
The SN74LV4051APWE4 is an equivalent variant often listed as a direct replacement. Check pinout compatibility and electrical specifications before substitution. Other family members like SN74LV4051ADR offer different packaging options such as SOIC-16.
