The MC74HC4051DWR2 is a high-speed silicon-gate CMOS analog multiplexer/demultiplexer with a single-pole eight-throw configuration (SP8T). This device is pin-for-pin compatible with the CD4051B, and is designed for use in analog or digital signal selection applications. It features a wide operating voltage range and low on-resistance, making it suitable for a variety of signal routing applications. The device also features an Enable input, which when HIGH, disables all switches to the OFF state.

Applications

• Analog signal multiplexing
• Audio signal routing
• Video signal switching
• Data acquisition systems
• Test equipment

Features

• High Speed: Propagation Delay = 14 ns (typ) at VCC = 5V
• Low Power Dissipation: ICC = 4 μA (max) at TA = 25°C
• Wide Operating Voltage Range: 2 V to 12 V
• Low On-Resistance: RON = 70 Ohms (typ) at VCC = 5V
• High Off-Resistance: ROFF = 10^12 Ohms (typ)
• Control Inputs TTL-Compatible
• Enable Input for Switch Control

Benefits

• Efficient signal routing with minimal signal degradation.
• Reduced power consumption, extending battery life in portable devices.
• Wide operating voltage range accommodates various signal levels.
• Low on-resistance ensures minimal voltage drop across the switch.
• High off-resistance prevents signal leakage when the switch is off.

Additional Details

The MC74HC4051DWR2 is packaged in a SOIC-16 (Small Outline Integrated Circuit) package, ideal for surface mount technology. The device operates over a temperature range of -55°C to +125°C. The TTL-compatible control inputs simplify interfacing with digital logic circuits. The Enable input provides a convenient means to disable all switches simultaneously. The high off-resistance ensures minimal signal leakage and crosstalk between channels. The device is commonly used in applications where multiple analog signals need to be selectively routed to a single output, or vice versa. The low on-resistance helps maintain signal integrity in demanding analog signal processing applications.
