Overview
The NLVHCT4852ADTR2G is a dual four-channel analog multiplexer/demultiplexer manufactured by onsemi using silicon gate CMOS technology. It belongs to the HCT logic family and operates within a supply voltage range of 2 V to 6 V. The device features injection current effect control, allowing signals at disabled input channels to exceed the supply voltage or go to ground without affecting the enabled channel. It provides low power dissipation with a maximum ICC of 2 μA at 25 °C. The component is housed in a 16-TSSOP package and supports surface mount installation.
Feature Summary
- Injection current effect control prevents signal interference from disabled channels exceeding supply voltage ranges.
- Dual four-channel architecture enables simultaneous multiplexing and demultiplexing operations.
- High noise immunity ensures reliable performance in electrically noisy environments.
- Low static power consumption suitable for battery-operated applications.
Applications
- Automotive electronic systems requiring robust analog signal routing.
- Data acquisition systems utilizing high-impedance signal paths.
- Industrial control units managing multiple sensor inputs.
- Communication equipment handling analog signal switching.
Procurement Notes
Verify the specific suffix 'ADR2G' against official onsemi documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact temperature grade and manufacturing site requirements specified in the latest datasheet revision. Cross-reference the manufacturer's part number directly with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual 4:1 analog switching is required with HCT logic compatibility. The injection current protection feature makes it suitable for automotive applications where voltage spikes are common. Compare the 2 μA max ICC against other HCT series devices if power efficiency is critical. Verify that the 16-TSSOP package dimensions fit the target PCB layout constraints.
Part Context
This part is part of the M74HC/NLVHCT4852 family of dual 4-channel analog multiplexers. It shares pinout compatibility with the standard 4052 and 4852 series but offers improved noise immunity and lower power consumption due to CMOS technology. The 'NLV' prefix typically indicates automotive-grade qualification and specific manufacturing controls.
Replacement Considerations
Direct pin-compatible replacements include the M74HC4852 and MC74HC4852 variants from onsemi. Other manufacturers offering similar dual 4-channel analog muxes with injection current protection should be evaluated for matching Ron specifications and supply voltage ranges. Verify logic family compatibility (HCT vs HC) for voltage level interfacing.
