Nexperia 74HC4051D 8-Channel Analogue Multiplexer/Demultiplexer SOIC-16

The Nexperia 74HC4051D is an 8-channel analogue multiplexer/demultiplexer housed in a compact 16-pin SOIC package, designed for routing analogue or digital signals in a wide range of electronic applications.

This high-speed Si-gate CMOS device is specified in full compliance with the JEDEC standard JESD 7A and offers compatibility with low-power Schottky TTL (LSTTL) logic families. It is suited to applications ranging from professional audio equipment to sophisticated industrial control systems.

Overview

The device has three digital select inputs (S0 to S2) and an active LOW enable input. It provides eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). When the enable pin is LOW, one of the eight internal switches is selected and enters a low-impedance ON state, as determined by the select inputs. A HIGH signal on the enable input places all switches into a high-impedance OFF state, providing signal isolation.

Key Features

• Wide analogue input voltage range from -5V to +5V
• Typical low ON resistance of 80 ohms (at VCC - VEE = 4.5V), helping to minimise signal attenuation and distortion
• Integrated logic level translation for interfacing standard 5V digital logic with ±5V analogue signal domains
• Break-before-make switching, which prevents momentary shorting of channels during switching
• ESD protection for enhanced reliability in handling and operation
• Operating supply voltage from 2V to 10V
• Specified ambient temperature range from -40°C to +125°C
• Surface mount design in a 16-pin SOIC package

Applications

Suitable for professional audio equipment and sophisticated industrial control systems, and for other electronic designs requiring analogue or digital signal routing.
