Overview
The TMUX4053DYYR is a general-purpose CMOS multiplexer featuring three independent 2:1 switches. It operates on a single supply from 5V to 24V or dual supplies up to ±12V. The device supports bidirectional analog signals ranging from VSS to VDD and includes an active-low logic enable pin. Key electrical parameters include a typical on-resistance of 60Ω at 25°C, low capacitance of 3pF, and ESD protection rated at 2000V HBM. It functions within an ambient temperature range of -55°C to +125°C.
Feature Summary
- Supports bidirectional signal paths for flexible data routing
- Features rail-to-rail operation across the full supply voltage range
- Includes break-before-make switching to prevent signal overlap
- Compatible with 1.8V logic thresholds for TTL and CMOS systems
Applications
- Analog multiplexing and demultiplexing
- Factory automation and control systems
- Battery test equipment
- Medical instrumentation
- Grid infrastructure monitoring
Procurement Notes
Verify the specific package variant DYY (SOT-23-THIN, 16-pin) matches the design footprint. Confirm that the logic control inputs align with the system's voltage levels, as the device requires valid supply voltages for proper threshold interpretation. Ensure thermal management accounts for the junction-to-ambient resistance in the chosen layout configuration.
Selection Notes
Select this component when designing circuits requiring multiple independent 2:1 analog switches within a compact form factor. It is suitable for applications needing wide supply voltage flexibility, including asymmetric configurations. Consider the low capacitance and high off-isolation characteristics if signal integrity at higher frequencies is critical for the application.
Part Context
This part belongs to the TMUX405x family, which also includes the TMUX4051 (8:1, 1-channel) and TMUX4052 (4:1, 2-channel). All devices in this series share similar electrical characteristics and are designed to be pin-compatible with industry-standard 4051, 4052, and 4053 multiplexers, facilitating direct upgrades in existing designs.
Replacement Considerations
The datasheet indicates pin compatibility with industry standard 4051, 4052, and 4053 muxes. Verify that legacy replacements meet the modern specifications for low capacitance and 1.8V logic compatibility required by the TMUX405x series.
