Overview
The MUX508IWPWR is an analog multiplexer switch IC manufactured by Texas Instruments, featuring a single 8:1 channel configuration. It operates within a supply voltage range of 10V to 36V for single-supply or ±5V to ±18V for dual-supply applications. The device provides a maximum on-state resistance of 170 Ohms with a channel-to-channel matching of 2.4 Ohms. Switching performance includes a maximum turn-on time of 136ns and a turn-off time of 75ns. Key electrical characteristics include a charge injection of 0.3pC, off-state leakage current of 1nA, and typical off-state capacitance values of 2.4pF and 7.5pF. It supports a working temperature range from -40°C to +125°C.
Feature Summary
- Supports rail-to-rail operation across wide single and dual power supply ranges
- Features low charge injection and low input leakage currents for minimal signal error
- Provides TTL-compatible digital input thresholds for logic interface compatibility
Applications
- Data acquisition systems requiring high-impedance source switching
- Portable instrumentation utilizing low power consumption modes
- Signal routing in industrial control environments
Procurement Notes
Verify the specific suffix 'IWPWR' against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the ordering information matches the required 16-TSSOP form factor and industrial operating specifications before finalizing procurement orders.
Selection Notes
Select this component when an 8:1 single-ended analog multiplexer is required with low distortion characteristics. Consider the 170 Ohm on-resistance and 136ns switching speed for bandwidth and latency requirements. Verify that the 16-TSSOP package fits the available PCB footprint constraints.
Part Context
This part belongs to the MUX50x series of CMOS analog multiplexers from Texas Instruments. The series includes variants like the MUX509, which offers different channel configurations such as 4:1 differential or dual 4:1 single-ended setups. All devices share similar low-power and low-leakage design philosophies suitable for precision signal conditioning.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the MUX50x family or comparable TI analog switches based on pinout and electrical parameter compatibility.
