Overview
The TMUX4051DYYR is a CMOS analog multiplexer featuring an 8:1, 1-channel configuration housed in a 16-pin SOT-23-THIN package. It operates on a single supply voltage ranging from 5V to 24V or dual supplies up to ±12V. The device supports bidirectional signal paths with rail-to-rail operation and includes 1.8V logic compatible inputs for TTL and CMOS compatibility. Key electrical parameters include a maximum on-resistance of 60 Ohms at 25°C (24V supply), a bandwidth of 430 MHz, and off-isolation of -95 dB. It functions within an ambient temperature range of -55°C to +125°C.
Feature Summary
- Supports bidirectional analog and digital signals across the full supply voltage range.
- Features break-before-make switching to prevent short circuits during channel transitions.
- Includes active-low enable control and address decoding for precise channel selection.
- Provides robust electrostatic discharge protection rated at 2000V via the human body model.
Applications
- Analog multiplexing and demultiplexing systems
- Factory automation and industrial control interfaces
- Battery test equipment and power delivery monitoring
Procurement Notes
Verify the specific DYYR suffix indicates the SOT-23-THIN 16-pin package and reel packaging format. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering quantity aligns with the manufacturer's standard reel specifications to avoid partial reel handling issues.
Selection Notes
Select this component when an 8:1 multiplexing ratio is required in a compact surface-mount footprint. The wide supply voltage range accommodates both single-supply and dual-supply architectures. Verify that the 60 Ohm on-resistance and 430 MHz bandwidth meet the signal integrity requirements of the target application circuit.
Part Context
This device belongs to the TMUX405x family of general-purpose CMOS multiplexers. It is pin-compatible with industry-standard 4051, 4052, and 4053 muxes, facilitating direct upgrades or replacements in existing designs. The DYYR variant specifically denotes the thin small-outline transistor package optimized for space-constrained printed circuit board layouts.
Replacement Considerations
Direct pin-compatible substitutes include the TMUX4051PW and TMUX4051BQB variants from Texas Instruments. These alternatives share identical functional specifications but differ in physical package dimensions and thermal characteristics.
