Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MC74HC4051ADR2
Analog Switches, Multiplexers, Demultiplexers Overview
The MC74HC4051ADR2 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 supports an analog power supply range of 2.0 V to 12.0 V (VCC - VEE) and a digital control supply range of 2.0 V to 6.0 V (VCC - GND). Key electrical parameters include a maximum ON resistance of 190 Ω at VCC=4.5 V, a channel-to-channel ON resistance matching of 30 Ω, and a maximum OFF leakage current of 1.0 mA at VCC=VEE=-6.0 V. It 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.
- Provides diode protection on all inputs and outputs to guard against high static voltages.
- Features channel-select and enable inputs 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 and video signal switching applications
- Programmable gain amplifier input selection
Analog Switches, Multiplexers, Demultiplexers Procurement Notes
Verify the obsolete status of this specific part number before design finalization. Confirm that the 'R2' suffix corresponds to the tape and reel packaging format as indicated in historical ordering information. Ensure compliance with RoHS requirements if applicable to the project specifications.
Analog Switches, Multiplexers, Demultiplexers Selection Notes
Select the MC74HC4051ADR2G variant for active procurement needs, as it serves as the direct lead-free successor to the discontinued model. Evaluate the HC4851A if injection current protection is required for the application. Verify package availability in SOIC-16 or TSSOP-16 formats based on board space constraints.
Analog Switches, Multiplexers, Demultiplexers Part Context
This component belongs to the MC74HC4051A family of analog multiplexers. It shares pinout compatibility with the older metal-gate MC14051AB series. The device integrates 184 FETs and functions as a single-pole, eight-position switch controlled by three binary select lines and an enable input.
Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
MC74HC4051ADR2G is the confirmed lead-free replacement for this discontinued part. Other potential substitutes include the MC74HC4051ADTR2G in TSSOP-16 packaging.
