NEXPERIA 74HC4053D Triple 2-Channel Analogue Multiplexer/Demultiplexer, SOIC-16

The NEXPERIA 74HC4053D is a high-performance, triple single-pole double-throw (SPDT) analogue switch integrated circuit, configured as a 2:1 multiplexer/demultiplexer. Engineered for precision signal routing in both analogue and digital systems, this IC features three independent switches, each with a common input/output (nZ) that can be connected to one of two independent inputs/outputs (nY0, nY1) via a digital select input (Sn). A common digital enable input (E) controls all switches; a high logic level on E turns all switches off, providing a safe, high-impedance state.

A key advantage of the 74HC4053D is its exceptionally low on-resistance, which minimises signal attenuation and distortion. Typical values are 80Ω, 70Ω, and 60Ω at supply differentials (VCC-VEE) of 4.5V, 6.0V, and 9.0V respectively. This makes it ideal for applications requiring high signal fidelity. The device incorporates input clamp diodes, allowing the use of current-limiting resistors to interface inputs with voltages exceeding VCC, thereby enabling robust logic level translation. This feature permits seamless communication between 5V logic systems and ±5V analogue signals.

Designed for reliability, the switch features a typical break-before-make action, preventing momentary shorting during channel switching. It is fully compliant with JEDEC standard No. 7A, ensuring quality and interoperability. The device operates from a single supply voltage ranging from 2V to 10V and is housed in a compact, surface-mount SOIC-16 package, making it suitable for space-constrained PCB designs. Its wide operating temperature range of -40°C to +125°C guarantees stable performance in demanding industrial and commercial environments.
