Overview
The NLVHC4851ADR2G is a single 8-channel analog multiplexer/demultiplexer manufactured by onsemi using silicon gate C2MOS technology. It features injection current effect control, allowing signals at disabled input channels to exceed the supply voltage range or go to ground without affecting the enabled channel. The device operates with a wide supply voltage range of 2 V to 6 V and offers low power dissipation with ICC typically 2 μA at 25°C. On-resistance is typically 215 Ω at 3.0 V, 160 Ω at 4.5 V, and 150 Ω at 6 V. Propagation delay is typically 8.6 ns at 4.5 V. It provides high noise immunity with VNIH/VNIL at 28% of VCC(min) and ESD protection of 2000 V HBM.
Feature Summary
- Injection current effect control for automotive applications
- Wide operating supply voltage range from 2 V to 6 V
- High noise immunity and robust ESD performance
Applications
- Automotive signal switching where voltages exceed normal logic levels
- Data acquisition systems requiring analog signal routing
- Communication equipment needing reliable multiplexing
Procurement Notes
Verify the specific suffix 'NLV' indicates automotive grade qualification against the official datasheet. Confirm RoHS compliance status as standard HC series may vary. Ensure the 16-SOIC package dimensions match the design footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when injection current protection is required for inputs exceeding the supply rail. Compare on-resistance values at the specific operating voltage against other 74HC4851 variants. Verify that the 2 V to 6 V supply range aligns with the system power architecture and that the 16-SOIC package is suitable for the assembly process.
Part Context
This part belongs to the 74HC family of high-speed CMOS logic devices. It is functionally compatible with the NXP M74HC4851 and other industry-standard 8:1 multiplexers. The device serves as a key interface component for routing multiple analog or digital signals into a single channel in complex electronic circuits.
Replacement Considerations
Direct pin-compatible substitutes include MC74HC4851ADWR2G and M74HC4851MTR. Verify that alternative parts meet the same injection current protection specifications and automotive temperature ranges if applicable.
