Overview
The SN74HC4852DGVR is a dual 4-to-1 multiplexer/demultiplexer switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2V to 6V. The device features two independent circuits, each configured as an SP4T switch with a maximum on-resistance of 195 ohms and channel-to-channel matching of 3 ohms. Switching times are specified at a maximum of 39ns for turn-on and 78ns for turn-off. Leakage current is limited to 200nA, with off-state capacitance at 22pF. It functions within an ambient temperature range of -40°C to 85°C and is housed in a 16-TVSOP package.
Feature Summary
- Dual independent 4:1 multiplexing architecture
- High-speed switching capability
- Low leakage and capacitance characteristics
Applications
- Data selector circuits
- Signal routing in communication systems
- Multiplexed data acquisition systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging and material specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the production line. Cross-reference the component marking code with official documentation to prevent counterfeit substitution during sourcing.
Selection Notes
Select this component when dual independent signal paths are required within a compact surface-mount footprint. Ensure the operating voltage remains within the 2V to 6V range to maintain specified electrical performance. Verify that the 195-ohm on-resistance meets the signal integrity requirements of the target application circuit.
Part Context
This part belongs to the SN74HC4852 family of analog switches. It is distinct from logic gates like the SN74AHC00 or buffers like the SN74AHC244 due to its multiplexing function. The DGVR suffix indicates a tape-and-reel packaging format suitable for automated assembly processes.
Replacement Considerations
The TMUX1309PWR is listed as a recommended alternative by the manufacturer. Verify pin compatibility and electrical parameter alignment before substituting.
