Nexperia 74HCT4051D,118 Demultiplexer 1 74HCT SP8T Non-Inverting Multiplexer Demultiplexer 16-Pin SO-16 74HCT4051D,118

Nexperia 74HCT4051D,118 is a high-performance demultiplexer device housed in a 16-pin SO-16 surface mount package. This device is a single-pole octal-throw (SP8T) analog switch designed for precision multiplexer and demultiplexer applications where signal integrity and minimal distortion are critical.

Operating at supply voltages between 4.5V and 5.5V, it is suitable for a broad range of industrial, electronic, and laboratory applications including analog sensor signal multiplexing, audio switching, and digital logic control systems. The device supports temperatures from -40°C up to 125°C, ensuring reliable operation under harsh environmental conditions.

The device features three digital select inputs (S0, S1, and S2), eight independent analog input/outputs (Yn), and a common input/output (Z). A digital enable input (E) permits disabling the switches when set HIGH. Integrated clamp diodes protect against voltage spikes, enabling safer interfacing with diverse voltage levels through appropriate current limiting resistors.

Designed for low on-resistance (maximum 180Ω) with flat resistance characteristics, the 74HCT4051D,118 minimizes signal attenuation and enhances audio and signal switching quality. Reduced total harmonic distortion further improves audio applications.

This device offers wide voltage tolerance and over-voltage tolerant options, making it ideal for complex industrial and commercial electronics requiring robust multiplexer/demultiplexer solutions. It provides high electrostatic discharge (ESD) protection, increasing durability in factory and field environments.

Operates over a wide temperature range from -40°C to 125°C. Compatible with surface mount technology in SO-16 packaging. Suitable for industrial electronics, laboratory instrumentation, audio switching, and control systems.

Enables efficient multiplexing/demultiplexing to minimize PCB layout complexity. Incorporates high ESD protection for enhanced device lifespan. Low maximum on-state resistance reducing power loss and signal distortion. Includes integrated clamp diodes for voltage interfacing safety.

This product is essential for engineers designing multiplexing circuits in consumer electronics, industrial machinery, measurement equipment, and other applications requiring precise signal routing. The 74HCT4051D,118 ensures reliable, low noise, and efficient performance in demanding environments.
