Overview
The HEF4053BT/AUJ is a triple single-pole double-throw (SPDT) analog switch manufactured by Nexperia, housed in a 16-lead SO16 plastic small outline package (SOT109-1). It operates within a supply voltage range of 3.0 V to 15.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features three independent switches, each with a digital select input (Sn), two independent inputs/outputs (Y0, Y1), and a common input/output (Z). A shared active LOW enable input (E) controls the state of all switches simultaneously. Input clamp diodes allow interfacing with voltages exceeding VDD when current limiting resistors are used.
Feature Summary
- Triple SPDT analog switching architecture suitable for multiplexer/demultiplexer applications
- Wide supply voltage operation from 3.0 V to 15.0 V with CMOS low power dissipation
- Integrated input clamp diodes enabling interface to voltages beyond VDD
- ESD protection compliant with JEDEC standards (HBM > 2000 V, CDM > 1000 V)
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the ordering suffix AUJ corresponds to the SOT109-1 (SO16) package variant as specified in the official documentation. Confirm that the component meets the required environmental specifications for the intended operating temperature range of -40 °C to +125 °C. Ensure compatibility with the 3.0 V to 15.0 V supply voltage requirements for the specific application design.
Selection Notes
Select this component for designs requiring three independent bidirectional analog switches controlled by standard logic levels. Consider the ON resistance characteristics which vary with supply voltage and input signal amplitude. Verify that the load capacitance and transition rates align with the dynamic performance limits defined in the datasheet for the target frequency response.
Part Context
The HEF4053B belongs to the HEF4000B series of CMOS logic devices produced by Nexperia. This family is designed for general-purpose digital and analog switching applications. The HEF4053B specifically provides a compact solution for routing multiple analog signals through a single channel or combining signals, utilizing standard 16-pin packaging options for ease of integration into printed circuit boards.
Replacement Considerations
Direct pin-compatible replacements include the HEF4053BTT (TSSOP16 package) and other variants within the HEF4053B family. Verify package dimensions and lead pitch when substituting between SO16 and TSSOP16 formats. Ensure any alternative component matches the electrical specifications for supply voltage, ON resistance, and ESD protection levels.
