Overview
The SN74LV4052APWT is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, designed for operation within a 1.65V to 5.5V supply voltage range. It integrates two independent 4:1 analog switches controlled by common select inputs and an enable pin. The device supports bidirectional signal transmission with amplitudes up to the supply rail. Key electrical parameters include a maximum on-resistance of 75 ohms, propagation delay of 25 ns, and off-isolation of approximately 45 dB. It operates reliably across a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.
Feature Summary
- Dual independent 4:1 analog switching architecture sharing common control lines
- Bidirectional signal path capability for both analog and digital waveforms
- Low on-resistance and low crosstalk characteristics for signal integrity
- High electrostatic discharge protection exceeding standard JESD specifications
Applications
- Audio and video signal routing and channel selection
- Sensor signal multiplexing in data acquisition systems
- Digital control bus channel distribution
- Signal gating and isolation in telecommunications equipment
Procurement Notes
Verify the specific suffix 'PWT' corresponds to the 16-pin TSSOP package and reel packaging configuration. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the exact temperature grade and package variant required for the design.
Selection Notes
Select this component when a dual-channel 4:1 switching topology is required within a single package. It is suitable for designs needing low power consumption and wide supply voltage compatibility. Compare against SN74LV4051A for single-channel 8:1 needs or SN74LV4053A for triple 2:1 configurations. Verify that the 75-ohm on-resistance meets the signal loss budget of the application.
Part Context
This device belongs to the SN74LV4052A family of CMOS analog switches. It shares functional similarities with other members like the SN74LV4051A and SN74LV4053A but differs in channel count and configuration. The 'PWT' suffix specifically denotes the surface-mount TSSOP-16 package type and tape-and-reel shipping method used by Texas Instruments.
Replacement Considerations
Direct pin-compatible alternatives include the SN74LV4052ADBR (SSOP-16) and SN74LV4052APWR (TSSOP-16). Cross-reference datasheets to ensure identical electrical characteristics and package dimensions before substitution.
