Overview
The NMUX1308PWJ is a general-purpose, CMOS, bi-directional, 8-channel analog switch manufactured by Nexperia. It operates within a supply voltage range of 1.5 V to 5.5 V and features rail-to-rail operation on analog signal pins. The device integrates injection current control circuitry to isolate overvoltage spikes on disconnected pins, preserving measurement accuracy without external clamping components. Digital control inputs support 1.8 V logic thresholds across the full operating voltage range and are 5.5 V tolerant. The component utilizes a TSSOP16 plastic thin shrink small outline package (SOT403-1) with a body width of 4.4 mm.
Feature Summary
- SP8T-Z functionality with bi-directional analog signal paths
- Integrated injection current control for overvoltage spike isolation
- 1.8 V digital logic threshold compatibility across the entire supply voltage range
- Ioff protection circuitry preventing back-powering when supply voltage is zero
Applications
- Analog or digital multiplexing and demultiplexing
- System monitoring and diagnostics
- Enterprise computing systems
- Appliance control circuits
Procurement Notes
Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm packaging details such as reel quantity or tape specifications. Ensure the selected variant matches the required temperature range of -40 °C to +125 °C. Cross-reference the SOT403-1 package dimensions with the target PCB footprint to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component for designs requiring dual-source compatibility with industry-standard 4051 and 4851 devices. It is suitable for applications needing low-voltage GPIO interfacing without voltage translation due to its 1.8 V logic compatibility. Consider the integrated injection current control for environments prone to transient voltage spikes on long signal traces.
Part Context
The NMUX1308 belongs to the NMUX130x family of analog switches from Nexperia. This family includes the NMUX1309, which offers dual 4-channel configurations. Both variants share similar electrical characteristics and pinout compatibility, allowing for flexible design choices based on channel count requirements while maintaining consistent performance metrics and interface standards.
Replacement Considerations
The datasheet explicitly states that the NMUX1308 is dual source compatible with existing 4851 and 4051 devices. Designers can consider these industry-standard equivalents for direct pin-compatible replacements in legacy designs.
