Overview
The SN74HC4852N is a dual 4-to-1 channel analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single power supply ranging from 2 V to 6 V. The device features two independent circuits, each configured as a 4:1 switch. Key electrical parameters include a maximum on-resistance of 195 ohms and a channel-to-channel matching of 3 ohms. Switching times are specified with a maximum turn-on time of 39 ns and a turn-off time of 78 ns. The package is a 16-pin DIP (Dual In-line Package).
Feature Summary
- Dual independent 4-to-1 analog switching paths
- Injection-current effect control for signal integrity
- Wide single-supply voltage operation range
Applications
- Data acquisition systems requiring signal routing
- Audio signal switching applications
- Industrial process control instrumentation
Procurement Notes
Verify the package type carefully, as the 'N' suffix typically denotes a plastic DIP package, which differs from the TVSOP or SOIC variants often found in inventory. Confirm RoHS compliance status and check for any specific manufacturing date codes or obsolescence notices directly from Texas Instruments documentation before procurement.
Selection Notes
Select this component when dual isolated 4-to-1 analog switching is required within a low-voltage logic environment. Ensure the application voltage does not exceed the 6 V limit. Consider the 195 ohm on-resistance impact on signal attenuation for high-impedance sources compared to lower resistance alternatives.
Part Context
This part belongs to the standard 74HC series of high-speed CMOS logic devices. It is functionally compatible with other manufacturers' 74HC4852 equivalents, such as those from STMicroelectronics or Nexperia, provided pinouts and electrical characteristics align with the design requirements.
Replacement Considerations
Direct substitutes include the M74HC4852RM13TR from STMicroelectronics and the 74HC4852D from Nexperia. Verify that the replacement package matches the PCB footprint, as the N variant is DIP while others may be surface-mount.
