Overview
The TMUX1308DYYR is a general-purpose CMOS multiplexer featuring an 8:1, 1-channel single-ended configuration. It operates within a wide supply voltage range of 1.62 V to 5.5 V and supports bidirectional analog and digital signals from GND to VDD. The device incorporates internal injection current control to protect switches without external components. Key electrical parameters include a maximum on-resistance (RON) of 1700 Ω at 1.8 V and 270 Ω at 5 V, with a typical off-isolation of -110 dB at 100 kHz. Propagation delay ranges from 30 ns at 1.8 V to 10 ns at 5 V. It is housed in a 16-pin SOT-23-THIN package.
Feature Summary
- Internal injection current control eliminates the need for external diode and resistor networks.
- Back-powering protection provided by the absence of an ESD diode path to VDD.
- Fail-safe logic allows control pin voltages to be applied before the power supply.
- Pin-compatible with industry standard 4051 and 4851 multiplexers.
Applications
- Analog and digital multiplexing and demultiplexing
- Data center switch systems
- Remote radio unit (RRU) applications
- Electricity meter monitoring
- IP network camera signal routing
Procurement Notes
Verify the specific ordering suffix DYYR against the manufacturer's official documentation to confirm the SOT-23-THIN-16 package type and reel packaging format. Ensure that the component meets the required RoHS compliance standards as specified in the datasheet. Cross-reference the part number with the latest Texas Instruments product folder to confirm current production status and availability constraints.
Selection Notes
Select this component when a single-ended 8:1 multiplexer is required with rail-to-rail operation capabilities. The device is suitable for designs needing 1.8 V logic compatibility and low capacitance characteristics. Consider the thermal resistance metrics of the SOT-23-THIN package if operating near the upper temperature limits or under high power dissipation conditions.
Part Context
This device belongs to the TMUX13xx family of CMOS multiplexers, which also includes the TMUX1309 differential variant. The TMUX1308 series is designed to replace legacy industry-standard multiplexers while offering enhanced protection features like injection current control. It serves as a direct functional upgrade for general-purpose switching applications requiring bidirectional signal paths.
Replacement Considerations
The TMUX1308DYYR is explicitly documented as pin-compatible with industry standard 4051 and 4851 multiplexers. Designers replacing these legacy parts should verify that the new injection current control features do not conflict with existing circuit protections.
