HEF4053BTT,112

Overview

The HEF4053BTT,112 is a triple single-pole double-throw (SPDT) analog switch manufactured by Nexperia USA Inc. 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 (nY0 and nY1), and a common input/output (nZ). A shared enable input (E) controls the state of all switches simultaneously. At a 15 V supply, the typical ON resistance is 60 Ω with a maximum of 175 Ω, while the OFF-state leakage current is specified at 1000 nA. The component is housed in a TSSOP16 package (SOT403-1) with a body width of 4.4 mm.

Feature Summary

• Triple SPDT analog switch configuration suitable for multiplexer/demultiplexer applications

Applications

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

Procurement Notes

Verify the ordering suffix '112' against official Nexperia documentation to confirm the specific tape-and-reel packaging format and quantity. Ensure the requested part matches the TSSOP16 (SOT403-1) package outline dimensions provided in the datasheet. Confirm RoHS compliance status as per the latest product data sheet revision before finalizing procurement orders.

Selection Notes

Select this component when a triple SPDT analog switch is required for signal routing in systems operating between 3 V and 15 V. Consider the TSSOP16 package constraints regarding thermal derating above 91 °C. Evaluate the ON resistance variation across the full input voltage range and temperature spectrum to ensure signal integrity meets application requirements.

Part Context

The HEF4053B series belongs to the HEF CMOS logic family designed for general-purpose switching. The HEF4053B specifically provides three independent SPDT switches sharing a common enable line. This architecture allows efficient management of multiple signal paths using minimal control pins, making it suitable for compact circuit designs requiring analog or digital signal selection.

FAQ

How does the enable input (E) affect the switch states?

When the enable input E is HIGH, all switches are turned off regardless of the select inputs. When E is LOW, the switches operate according to the logic levels applied to their respective select inputs (Sn).

What is the maximum allowable input transition rate?

The recommended maximum input transition rise and fall rate depends on the supply voltage: 3.75 μs/V at 5 V, 0.5 μs/V at 10 V, and 0.08 μs/V at 15 V.

Does the device include input clamp diodes?

Yes, the inputs include clamp diodes, which enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.
