Overview
The MC74HC4851ANG is a single 8-channel analog multiplexer/demultiplexer manufactured using silicon gate C2MOS technology. It operates within a wide supply voltage range of 2 V to 6 V and features injection current effect control, allowing disabled channel signals to exceed the supply rails without affecting the enabled path. The device provides low power dissipation with a maximum static current of 2 μA at 25°C. It offers typical on-resistance values ranging from 150 Ω to 215 Ω depending on the supply voltage and includes high noise immunity and robust latch-up performance exceeding 500 mA per JESD 17 standards.
Feature Summary
- Injection current effect control enables signal integrity when disabled channels experience voltages outside the supply range.
- Wide operating supply voltage range supports diverse logic and analog interface requirements.
- High noise immunity ensures reliable operation in electrically noisy environments.
- Robust ESD protection and latch-up performance enhance device durability.
Applications
- Automotive electronic systems requiring signal routing under varying voltage conditions.
- Data acquisition systems utilizing multiple analog input channels.
- Industrial control circuits needing isolated signal switching.
Procurement Notes
Verify the specific suffix 'G' for RoHS compliance status against the latest manufacturer documentation, as historical data indicates variations. Confirm the package type corresponds to the required PCB footprint. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications to avoid handling discrepancies during assembly.
Selection Notes
Select this component when an 8:1 analog switch with injection current protection is required. Compare on-resistance and propagation delay specifications against system timing constraints. Evaluate the 16-SOIC package dimensions for board space limitations. Consider the MC74HCT4851A variant if LSTTL-compatible input levels are necessary instead of standard HC logic levels.
Part Context
This part belongs to the 74HC series of CMOS logic devices, specifically designed as analog multiplexers. It is functionally compatible with the legacy 4051 and 4851 series while offering improved performance characteristics typical of modern CMOS technology. The device serves as a critical interface component for routing multiple analog signals through a single channel in complex electronic architectures.
Replacement Considerations
The MC74HC4851ADG is a verified alternative offering identical functionality in a tube package rather than tape and reel. The MC74HCT4851A provides similar multiplexing capabilities but features LSTTL-compatible inputs, which may require voltage level adjustments for direct replacement in existing designs.
