HEF4052BT/AUJ

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4052BT/AUJ is a dual single-pole quad-throw analog switch (2x SP4T) manufactured by Nexperia. It operates within a supply voltage range of 3.0 V to 15.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features two independent multiplexers, each with four inputs/outputs (nY0-nY3) and a common input/output (nZ). Key electrical parameters include an ON resistance maximum of 2500 Ω at 5 V and 175 Ω at 15 V. Propagation delays are specified up to 305 ns, while OFF-state leakage current reaches 1000 nA at 15 V. The component utilizes a 16-lead SOIC package.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the enable input function?

The active LOW enable input (E) controls the state of all switches. When E is HIGH, all switches turn off regardless of select inputs. When E is LOW, one channel is selected based on S1 and S2.

What is the maximum supply voltage?

The recommended operating conditions specify a maximum supply voltage (VDD) of 15.0 V relative to VSS.

Does the device support break-before-make switching?

Yes, using the enable input allows for break-before-make operation. Switching E HIGH turns all switches off before selecting a new channel via S1 and S2.
