MC74HC4051ADG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC74HC4051ADG is a single-channel, 8-to-1 analog multiplexer/demultiplexer manufactured by onsemi in a 16-pin SOIC package. It utilizes silicon-gate CMOS technology to provide fast switching speeds and low ON resistance. The device supports a digital supply voltage (VCC) range of 2.0 V to 6.0 V and an analog supply range (VCC - VEE) of 2.0 V to 12.0 V. Key electrical parameters include a maximum ON resistance of 100 Ω at VCC = 6.0 V, a channel-to-channel ON resistance matching of 10 Ω, and a maximum OFF leakage current of 200 nA. The component operates within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate counterparts.
• Features diode protection on all inputs and outputs to guard against high static voltages.
• Provides low crosstalk between switches and low noise performance.
• Compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used.

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog signal routing in data acquisition systems
• Audio signal switching and processing
• Test and measurement equipment signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-16 package and 'G' indicates Pb-Free compliance as per the manufacturer's ordering information. Confirm that the component meets RoHS requirements if applicable to your assembly process. Check for any automotive-specific prefixes or suffixes if AEC-Q100 qualification is required for your application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch is needed with a wide analog voltage swing capability up to 12 V across supplies. Ensure the digital control logic operates within the 2 V to 6 V range. Consider the 100 Ω ON resistance and 130 pF off-capacitance for bandwidth and isolation requirements. Verify that the SOIC-16 package dimensions fit the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC74HC4051A family of high-performance silicon-gate CMOS analog multiplexers. It shares pinout compatibility with older metal-gate devices like the MC14051AB. The 'D' suffix denotes the SOIC-16 package, while 'G' signifies lead-free packaging. It is distinct from the HC4052A (4:1) and HC4053A (2:3) variants in channel count and configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MC74HC4051ADR2G is a tape-and-reel version of the same device. MC74HC4051ADWG offers the same functionality in a wide SOIC-16 package. For TSSOP packages, consider MC74HC4051ADTR2G. Cross-manufacturer equivalents such as Nexperia 74HC4051PW may be evaluated for pin compatibility and electrical specifications.
