Overview
The NJU211M is a quad SPST analog switch manufactured by Nisshinbo Micro Devices Inc. utilizing CMOS technology. It features a high breakdown voltage of 40V and adjustable input threshold levels controlled by an external voltage supply. The device operates within a temperature range of 0°C to +70°C and supports dual power supplies up to ±15V. Key electrical parameters include a maximum on-resistance of 175 Ohms, a maximum operating time of 1 µs, and a maximum off-time of 500 ns. The component is housed in a DMP-16 surface-mount package.
Feature Summary
- High breakdown voltage capability up to 40V for robust operation
- Adjustable logic input threshold via external control voltage
- Functionally and pin-to-pin compatible with SILICONIX DG211A
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs
- Break-before-make switching applications
Procurement Notes
Verify the specific package variant during procurement as the DIP16 configuration is designated as Not Recommended for New Design (NRND) since February 2023. Confirm that the DMP-16 package aligns with current design requirements. Ensure compatibility with existing board layouts if replacing older components. Check for updated availability status directly with the manufacturer or authorized distributors before finalizing orders.
Selection Notes
Select this component when a quad SPST switch with high voltage tolerance is required. The adjustable threshold allows flexibility in interfacing with various logic families. Consider the DMP-16 package for surface-mount designs, noting that the DIP version is obsolete. Verify that the 175 Ohm on-resistance meets the signal integrity requirements of the application circuit.
Part Context
The NJU211 belongs to the NJU211 series of analog switches from Nisshinbo Micro Devices. This series provides multiple channel configurations for signal switching tasks. The NJU211 specifically offers four independent single-pole single-throw channels. It serves as a direct replacement for legacy silicon-based switches in industrial and consumer electronics.
Replacement Considerations
The NJU211 is functionally and pin-to-pin compatible with the SILICONIX DG211A. When replacing the discontinued DIP16 version, ensure the DMP-16 package fits the footprint or modify the PCB layout accordingly.
