Overview
The SN74HC4852PW is a dual 4-to-1 channel analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +125°C. The device is housed in a 16-pin TSSOP package with dimensions of 9.9 x 3.91 x 1.58 mm. It features injection-current effect control to maintain signal integrity during switching operations.
Feature Summary
- Dual independent 4-to-1 analog signal routing paths
- Integrated injection-current effect control for improved signal fidelity
- Wide operational voltage compatibility across standard logic families
Applications
- Analog signal routing in data acquisition systems
- Multi-channel sensor interface circuits
- Audio signal switching applications
Procurement Notes
Verify the specific suffix 'PW' confirms the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's current documentation, as environmental declarations may vary by production batch. Ensure the supplier provides official datasheets matching the SN74HC4852 designation to avoid confusion with similar multiplexer families.
Selection Notes
Select this component when dual independent analog channels are required within a single package. The HC series offers high-speed performance suitable for general-purpose digital and analog switching. Verify that the 2V minimum supply voltage meets the system requirements, as lower voltages may not ensure proper logic threshold levels.
Part Context
This part belongs to the SN74HC family of high-speed CMOS logic devices. It serves as an analog switch solution distinct from digital logic gates. The device complements other multiplexers like the SN74HC4052 but includes specific enhancements for controlling charge injection effects during state transitions.
Replacement Considerations
The SN74HC4052 is a functional equivalent but lacks the specific injection-current control features documented for the 4852 series. Verify pinout compatibility before substitution. Other variants such as SN74HC4852D or SN74HC4852DG4 offer identical functionality with different packaging options.
