The 74V4051MTC is an 8-channel analog multiplexer/demultiplexer from Fairchild Semiconductor (now ON Semiconductor). This device allows for the selection of one of eight analog signals to be transmitted to a common output. It is designed for low-voltage operation and is suitable for a variety of analog signal routing applications.

Applications

• Analog signal multiplexing
• Audio and video signal routing
• Data acquisition systems
• Sample-and-hold circuits

Features

• Low On-Resistance: Typically 80 Ohms at VCC = 5V
• Wide Operating Voltage Range: 2V to 6V
• Low Power Consumption: ICC = 2 µA (max) at VCC = 5V
• Break-Before-Make Switching Action
• Control Inputs TTL Compatible

Benefits

• Versatile Signal Routing: Allows selection of one of eight analog signals.
• Low Signal Distortion: Low on-resistance minimizes signal loss and distortion.
• Wide Operating Voltage: Suitable for a broad range of applications.
• Reduced Power Consumption: Low power consumption extends battery life in portable devices.
• Prevent Short Circuits: Break-before-make switching prevents momentary short circuits when switching channels.

Additional Details

The 74V4051MTC selects one of eight channels determined by the binary address applied to the A, B, and C control inputs. Enable input (E) disables all channels when HIGH. The channels are bilateral switches, allowing them to be used as either multiplexers or demultiplexers. The device is TTL compatible, simplifying interfacing with other TTL logic devices. The operating temperature range is typically -40°C to +85°C. This multiplexer/demultiplexer is ideal for applications requiring efficient routing of analog signals, such as audio mixers, data acquisition, and process control systems.
