Overview
The TMUX1575YCJR is a CMOS analog switch featuring four independent 2:1 (SPDT) channels in a 16-pin WLCSP package. It operates on a single supply voltage ranging from 1.08V to 3.6V with an active supply current of 7µA typical. The device supports bidirectional signal paths up to VDD x 2, capped at a maximum input/output voltage of 3.6V. Key electrical parameters include a maximum on-resistance of 8Ω, a bandwidth of 1.8GHz, and off-isolation of -95dB at 100kHz. It functions within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Powered-off protection isolates the signal path when supply voltage is removed, preventing back-powering through internal ESD diodes.
- Fail-safe logic allows control pin voltages to be applied before the supply rail without damaging the device.
- Integrated pull-down resistors on logic pins eliminate the need for external components, reducing system size.
- 1.2V logic compatible inputs enable direct interfacing with low-voltage processors without external translation.
Applications
- Flash memory sharing
- JTAG multiplexing
- SPI multiplexing
- eMMC multiplexing
- Smart watches
Procurement Notes
Verify the specific suffix 'YCJR' corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the 16-WLCSP footprint matches the target PCB layout dimensions. Ensure the operating environment stays within the specified thermal limits to maintain performance reliability.
Selection Notes
Select this component when designing systems requiring high-speed signal switching with minimal power consumption. The wide supply range and beyond-supply operation make it suitable for low-voltage portable electronics. Verify that the 1.2V logic thresholds align with the controlling microcontroller's GPIO levels to ensure proper switching states.
Part Context
This part belongs to the Texas Instruments TMUX1575 family of high-speed analog switches. It is specifically designed for applications demanding small form factors and low power, such as mobile phones, servers, and data center infrastructure. The device integrates features like fail-safe logic and powered-off protection to simplify system design.
Replacement Considerations
Check for alternative packages or suffixes within the same TMUX1575 family if different reel quantities are needed. Verify compatibility with existing board layouts when considering substitutes from other manufacturers, ensuring pinout and electrical characteristics match.
