Overview
The MC74HC4051AFELG is a single-channel, 8-position analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to achieve fast switching speeds 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 maximum propagation delay of 45 ns at VCC = 6.0 V, and a typical bandwidth of 80 MHz. It features diode protection on all inputs and outputs, low crosstalk, and low off-channel leakage current.
Feature Summary
- Utilizes silicon-gate CMOS technology for high-speed switching and low power consumption
- Provides improved linearity and lower ON resistance compared to metal-gate counterparts
- Includes diode protection circuitry on all inputs and outputs to guard against static discharge
- Compatible with standard CMOS logic levels and LSTTL outputs when pull-up resistors are used
Applications
- Analog signal routing in data acquisition systems
- Audio and video signal switching applications
- Programmable gain amplifiers and sensor multiplexing
- Test and measurement equipment requiring multi-channel signal selection
Procurement Notes
Verify the specific ordering suffix 'FEL' corresponds to the SOEIAJ-16 package and tape-and-reel shipping configuration. Confirm that the 'G' suffix indicates a lead-free package compliant with RoHS standards. Ensure the component matches the manufacturer's marking diagram for the MC74HC405xA series before integration into production.
Selection Notes
Select this component when an 8-channel analog switch is required within a compact SOEIAJ-16 footprint. Verify that the operating voltage requirements align with the 2.0 V to 6.0 V digital supply range. Consider the 100 Ω maximum ON resistance and 45 ns propagation delay specifications to ensure compatibility with the target signal frequencies and impedance matching requirements.
Part Context
This part belongs to the MC74HC405xA family of high-performance silicon-gate CMOS analog multiplexers. It shares pinout compatibility with older metal-gate devices like the MC14051AB. The device is functionally identical to the non-Pb-Free version MC74HC4051AFEL, differing only in packaging compliance. It is distinct from the HC4052A (4-channel) and HC4053A (dual 2-channel) variants in the same datasheet.
Replacement Considerations
Direct functional substitutes include other 8-channel analog muxes such as the SN74HC4051 or CD74HC4051. For pin-compatible replacements in the SOEIAJ-16 package, verify the availability of equivalent parts from manufacturers like Texas Instruments or Toshiba. Ensure replacement components meet the same voltage and speed specifications.
