SN74LV4052ADRE4

Overview

The SN74LV4052ADRE4 is a dual 4-channel analog multiplexer/demultiplexer from Texas Instruments, part of the SN74LV4052A series. It operates on a single supply voltage ranging from 1.65V to 5.5V and supports bidirectional signal transmission with amplitudes up to 5.5V (peak). The device integrates two independent 4:1 analog switches controlled by common select inputs (A, B) and an enable input (INH). Key electrical parameters include a nominal bandwidth of approximately 50 MHz, off-isolation of about 45 dB, and latch-up performance exceeding 100 mA per JESD 78 Class II standards. It features ESD protection ratings of 2000V HBM and 1000V CDM. The component is housed in a 16-pin TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual independent 4:1 analog switching architecture for simultaneous signal routing
• Low on-resistance and low crosstalk characteristics inherent to CMOS technology
• High electrostatic discharge protection ensuring robustness in sensitive environments
• Bidirectional signal flow capability supporting both analog and digital waveforms

Applications

• Signal gating and isolation in telecommunications equipment
• Audio and video signal path selection in consumer electronics
• Sensor signal multiplexing in data acquisition systems
• Modulation and demodulation circuits in communication devices

Procurement Notes

Verify the specific RE4 suffix against the manufacturer's current documentation to confirm compliance with RoHS directives and lead-free manufacturing processes. Ensure the ordering information matches the required TSSOP-16 package variant. Cross-reference the datasheet revision date to validate that all electrical specifications and mechanical dimensions align with your design requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring dual independent analog channels within a low-voltage environment. The SN74LV4052ADRE4 is suitable for applications demanding high-speed switching with minimal signal distortion. Consider the 1.65V minimum operating voltage for compatibility with modern low-power logic families. Evaluate the 50 MHz bandwidth to ensure it meets the frequency requirements of the intended analog signals.

Part Context

This device belongs to the SN74LV4052A family of dual 4-channel analog multiplexers. It shares functional similarities with other members like the SN74LV4051A and SN74LV4053A but differs in channel configuration. The RE4 suffix typically denotes environmental compliance and packaging specifics within the Texas Instruments portfolio. It serves as a solid-state alternative to mechanical relays or discrete switch arrays.

Replacement Considerations

Direct pin-compatible alternatives include the SN74LV4052ADBVR and SN74LV4052ADBR. Verify if the RE4 suffix implies specific tape-and-reel quantities or material changes compared to standard variants. Check for automotive-grade equivalents such as the SN74LV4052A-Q1 if higher reliability standards are required.
