Overview
The TMUX4053PWR is a general-purpose CMOS multiplexer switch IC featuring three independent 2:1 switches in a 16-pin TSSOP package. It operates on a single supply from 5V to 24V, dual supplies up to ±12V, or asymmetric configurations. The device supports bidirectional analog signals ranging from VSS to VDD with rail-to-rail operation. Key electrical parameters include a maximum on-resistance of 240Ω at 24V, typical off-isolation of -95dB, and low capacitance of 3pF. Logic inputs are compatible with 1.8V thresholds, ensuring compatibility with TTL and CMOS logic families.
Feature Summary
- Supports bidirectional signal paths with rail-to-rail voltage operation across wide supply ranges
- Features 1.8V logic-compatible control inputs for seamless integration with modern microcontrollers
- Incorporates break-before-make switching to prevent short circuits during channel transitions
Applications
- Analog multiplexing and demultiplexing systems
- Factory automation and industrial control interfaces
- Battery test equipment signal routing
- Medical instrumentation data acquisition
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing components. Confirm that the requested quantity matches standard reel sizes provided by distributors. Ensure compliance with RoHS directives as indicated in official documentation before finalizing procurement orders.
Selection Notes
Select the TMUX4053PWR when a design requires three independent SPDT switches rather than a single high-channel-count multiplexer. This component is suitable for applications needing 1.8V logic compatibility and wide supply voltage flexibility. Verify that the required bandwidth and leakage current specifications align with the device's AC performance characteristics.
Part Context
The TMUX4053PWR belongs to the Texas Instruments TMUX405x family of analog switches. This series includes the TMUX4051 (8:1) and TMUX4052 (4:1) variants, all sharing pin compatibility with industry-standard 4051, 4052, and 4053 muxes. The PWR suffix specifically denotes the plastic small-outline package with exposed thermal pad.
Replacement Considerations
Direct pin-compatible replacements include other members of the TMUX405x family such as the TMUX4051PW or TMUX4052PW. Legacy equivalents like the CD4053BPWR may be considered if lower speed and higher on-resistance are acceptable within the system design constraints.
