HEF4052BT-Q100,118

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4052BT-Q100 is a dual single-pole quad-throw analog switch (2x SP4T) designed for analog or digital 4:1 multiplexer and demultiplexer applications. It features four independent inputs/outputs and one common input/output per switch, controlled by shared digital select inputs and an active LOW enable input. The device operates within a supply voltage range of 3.0 V to 15.0 V and is qualified to AEC-Q100 Grade 1 standards. It supports ambient temperatures from -40 °C to +125 °C and includes input clamp diodes for overvoltage protection.

• Wide supply voltage range from 3.0 V to 15.0 V
• Fully static operation with high noise immunity
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog multiplexing and demultiplexing
• Digital multiplexing and demultiplexing
• Signal gating

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant against the ordering code; 'BT' indicates the SO16 plastic small outline package (SOT109-1). Confirm that the application environment remains within the specified -40 °C to +125 °C temperature range. Ensure supply voltages do not exceed the absolute maximum ratings of 18 V to prevent permanent damage. Check for compliance with JEDEC standard JESD 13-B if required by system specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel analog switching solution is required for automotive-grade designs. The shared control logic simplifies circuit design by using common select inputs for both switches. Consider the ON resistance variations across different supply voltages and input signal levels when designing precision analog paths. Verify that the total power dissipation limits are respected under the expected thermal conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Nexperia HEF4052B-Q100 family of dual 4-channel analog multiplexers. It is specifically manufactured in the SO16 plastic small outline package (SOT109-1), which provides a body width of 3.9 mm. The device is suitable for use in automotive applications due to its AEC-Q100 Grade 1 qualification.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The HEF4052BTT-Q100 serves as a functional alternative, offering identical electrical characteristics but housed in a TSSOP16 package (SOT403-1). Designers must account for the physical footprint differences between the SO16 and TSSOP16 packages when substituting components.
