Overview
The TMUX4051PWRQ1 is an automotive-grade, 8:1, 1-channel CMOS multiplexer from Texas Instruments. It operates with a single supply voltage range of 5 V to 24 V or dual supplies up to ±12 V. The device supports bidirectional analog signals ranging from VSS to VDD and features 1.8-V logic compatible thresholds for TTL and CMOS compatibility. Key electrical parameters include a typical on-resistance (RON) of 60 Ω at 25°C, off-isolation of -95 dB at 1 MHz, and crosstalk of -90 dB at 1 MHz. It exhibits low capacitance of 3 pF and provides ESD protection of 2000 V per the human body model. The component is qualified under AEC-Q100 standards for Grade 1, supporting an ambient operating temperature range of –40°C to 125°C.
Feature Summary
- AEC-Q100 qualified for automotive applications with extended temperature support
- Bidirectional signal path enabling rail-to-rail operation across wide supply ranges
- Break-before-make switching prevents simultaneous connection of multiple inputs
- Pin-compatible with industry standard 4051 and 4052 multiplexers
Applications
- Analog multiplexing and demultiplexing
- Battery management systems (BMS)
- HVAC control modules
- Telematics systems
- On-board charging and wireless charging
Procurement Notes
Verify that the ordering suffix 'PWR' corresponds to the TSSOP-16 package variant required for your design. Confirm the 'Q1' suffix indicates AEC-Q100 automotive qualification. Ensure the specific revision level matches your documentation requirements. Cross-reference the manufacturer part number against official datasheets to confirm pinout and electrical specifications before finalizing procurement orders.
Selection Notes
Select this component when an 8:1 multiplexing configuration is required in an automotive environment. It is suitable for designs needing wide supply voltage flexibility between 5 V and 24 V. Consider this device if pin compatibility with legacy 4051/4052 muxes is necessary for board layout reuse. Verify that the 60 Ω on-resistance meets the signal integrity requirements of your specific application circuit.
Part Context
The TMUX4051PWRQ1 belongs to the TMUX405x-Q1 family of general-purpose CMOS multiplexers. This family includes the TMUX4052-Q1, which offers a 4:1, 2-channel configuration. Both devices share similar electrical characteristics and automotive qualifications but differ in channel count and address input requirements. The PWR suffix specifically denotes the 16-pin Thin Shrink Small Outline Package (TSSOP).
Replacement Considerations
The TMUX4051-Q1 is explicitly stated to be pin-compatible with industry standard 4051 and 4052 multiplexers. Designers replacing legacy parts should verify that the on-resistance and leakage current specifications of the original component are within the limits of the TMUX4051PWRQ1.
