Overview
The SN74HC4852D is a dual 4-to-1 channel analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single power supply ranging from 2V to 6V and features a maximum on-resistance of 195 ohms with a channel-to-channel matching of 3 ohms. The device includes two independent circuits, each capable of switching four inputs to one output or vice versa. Key electrical parameters include a maximum switch time of 39ns for turn-on and 78ns for turn-off, along with an off-state leakage current of 200nA. It is housed in a 16-DIP package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Dual independent 4-to-1 analog signal routing capability within a single package
- Injection-current effect control to minimize signal distortion during switching
- Low on-resistance with tight channel-to-channel matching for consistent signal integrity
- Wide single-supply voltage operation compatible with standard logic levels
Applications
- Data acquisition systems requiring multi-channel signal selection
- Audio signal routing and switching applications
- Industrial process control instrumentation
- Communication equipment signal path management
Procurement Notes
Verify the specific suffix 'D' corresponds to the 16-pin DIP package when sourcing. Confirm RoHS compliance status as manufacturing processes may update component specifications over time. Ensure the supplier provides official datasheets to validate pinout and electrical characteristics against the original Texas Instruments documentation before integration into designs.
Selection Notes
Select this component when dual independent 4:1 analog switching is required within space-constrained designs using through-hole technology. Compare on-resistance and leakage current specifications against alternative logic families if low-power consumption is critical. Verify that the 2V to 6V supply range aligns with the system's available voltage rails and that the 195-ohm resistance does not degrade signal quality for the intended application bandwidth.
Part Context
The SN74HC4852 belongs to the HC (High-speed CMOS) logic family, offering faster switching speeds compared to standard 74C series devices while maintaining low power consumption. It serves as a functional equivalent to other dual 4-channel multiplexers but distinguishes itself through integrated injection-current control features designed to improve analog signal fidelity in mixed-signal environments.
Replacement Considerations
The SN74HC4852DE4 and SN74HC4852DG4 are confirmed equivalents from Texas Instruments with identical functionality. Cross-manufacturer alternatives such as the NXP 74HC4052 or STMicroelectronics M74HCT4052 share similar topologies but require verification of pin compatibility and electrical parameter alignment.
