HEF4053BT/AUJ

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
