Overview
The MUX36D08IDWR is a precision analog multiplexer manufactured by Texas Instruments, featuring an 8:1 configuration within a single circuit. It operates on a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. The device is housed in a 16-pin TSSOP package with exposed pad. Key electrical characteristics include a maximum on-state leakage current of 1 pA and a typical off-state leakage current of 40 pA. The on-resistance is specified at a maximum of 250 Ohms, with a channel-to-channel matching of 6 Ohms. Switching times are characterized by a maximum turn-on time of 151 ns and a maximum turn-off time of 90 ns.
Feature Summary
- Ultra-low on-state leakage current specification for high-impedance signal integrity
- Precision analog switching with tight channel-to-channel resistance matching
- High breakdown voltage capability supporting wide single and dual supply ranges
Applications
- Data acquisition systems requiring low leakage
- Medical instrumentation signal routing
- Industrial process control multiplexing
Procurement Notes
Verify the specific suffix IDWR against the manufacturer's official datasheet to confirm the TSSOP-16 package variant and reel packaging quantity. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling procedures prior to assembly.
Selection Notes
Select this component when designing circuits that demand minimal signal distortion due to extremely low leakage currents. The 36 V rating allows compatibility with higher voltage signal rails compared to standard 5 V logic switches. Consider the 151 ns switching speed for applications where moderate bandwidth is sufficient.
Part Context
This part belongs to the MUX36xxx family of CMOS analog multiplexers designed for precision applications. The 'D' designation typically indicates specific performance thresholds regarding leakage and resistance compared to other series variants like the S-series. It serves as a robust solution for replacing mechanical relays in solid-state switching environments.
Replacement Considerations
Direct functional substitutes within the same family include the MUX36S08IDWR, which shares similar pinouts but may differ in specific leakage or resistance parameters. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
