MC74HC4051ADTG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC74HC4051ADTG is a discontinued single-pole, eight-position analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to achieve fast propagation delays and low ON resistance. The device operates with a digital supply voltage (VCC) ranging from 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 matching (ΔRon) of 10 Ω, and a bandwidth of 80 MHz. It features a 16-TSSOP package with an operating 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.
• Provides diode protection on all inputs and outputs to guard against high static voltages.
• Features low crosstalk between switches and low noise performance suitable for precision applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog signal routing in data acquisition systems
• Audio switching and signal path selection
• Programmable gain amplifiers and sensor multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the discontinuation status directly with onsemi or authorized distributors before design finalization. Confirm that the TSSOP-16 package dimensions match the target PCB footprint. Ensure compliance with RoHS and lead-free requirements if applicable to the end product specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component only if the 16-TSSOP package is mandatory and the specific HC logic family characteristics are required. Evaluate alternative packages such as SOIC-16 or Tape & Reel variants if availability is critical. Verify that the 100 Ω ON resistance meets the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC74HC4051A series of analog multiplexers. It shares functional compatibility with other members like the MC74HC4052A and MC74HC4053A but differs in channel configuration. The 'DT' suffix indicates the TSSOP-16 package, while 'G' denotes a Pb-Free compliant manufacturing process.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MC74HC4051ADR2G: Same function, different packaging (Tape & Reel). MC74HC4051ADG: Same function, different packaging (Tube/SOIC-16). Check datasheet for pinout and electrical parameter equivalence before substitution.
