HEF4052BTT,112

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4052BTT,112 is a dual single-pole quad-throw analog switch manufactured by Nexperia USA Inc. It features two independent SP4T switches with common inputs/outputs (nZ) and four independent inputs/outputs (nY0 to nY3) per switch. The device operates on a single supply voltage ranging from 3.0 V to 15.0 V. It utilizes a TSSOP16 plastic thin shrink small outline package (SOT403-1) with a body width of 4.4 mm. The component supports an ambient temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that the requested part number aligns with the current product data sheet revision to avoid discrepancies in pin configuration or electrical characteristics during procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring dual 4:1 analog signal routing within a compact surface-mount footprint. Consider the maximum ON resistance values at the intended operating voltage and verify that the required propagation delays meet the system timing constraints under the specified load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the HEF4052B family of dual 4-channel analog multiplexer/demultiplexers. It shares functional logic with other variants in the series but differs in physical packaging. The TSSOP16 version provides a smaller form factor compared to standard SO16 packages while maintaining identical electrical performance and pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers FAQ

How are the digital select inputs controlled?

The device uses two digital select inputs (S1 and S2) and an active LOW enable input (E). When E is HIGH, all switches are turned off regardless of the state of S1 and S2.

What is the function of the input clamp diodes?

The inputs include clamp diodes that allow the use of current limiting resistors to interface inputs to voltages exceeding the positive supply voltage (VDD).

What is the maximum supply voltage range?

The recommended operating conditions specify a supply voltage range from 3.0 V to 15.0 V.
