Overview
The SN74HC4852PWR 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. The device features two independent 4:1 multiplexing circuits in a 16-pin TSSOP package. 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 39ns and turn-off time of 78ns. The input capacitance is 22pF, and the off-state leakage current is limited to 200nA. It supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Dual independent 4-to-1 analog signal routing capability
- Injection-current effect control for improved signal integrity
- CMOS compatible logic inputs with wide voltage operation
Applications
- Data acquisition systems requiring analog signal selection
- Audio signal routing and switching applications
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix PWR indicates the PolyPack TSSOP-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the exact package and tape-and-reel specifications required for the assembly line.
Selection Notes
Select this component when dual independent 4-to-1 analog switching is required within a low-power CMOS environment. Compare against the SN74HC4052 family if pinout compatibility is critical, noting that the HC4852 offers injection-current control. Verify that the 195-ohm on-resistance meets the signal attenuation requirements of the target application circuit.
Part Context
This part belongs to the SN74HC485x series of high-speed CMOS analog switches. It shares functional similarities with the SN74HC4052 but includes specific design improvements for injection-current effects. The device is part of Texas Instruments' standard logic portfolio, widely used in mixed-signal applications requiring reliable analog path selection.
Replacement Considerations
The SN74HC4852DR serves as a direct pin-compatible alternative with a SOIC-16 package. Other potential substitutes include the SN74HC4052 series, though pinouts may differ. Verify electrical characteristics and package dimensions before substituting.
