Overview
The NJU201AM is a CMOS quad SPST analog switch from Nisshinbo Micro Devices, housed in a 16-DMP surface-mount package. It features high breakdown voltage protection up to 44V and low on-state resistance, approximately half that of the NJU7301. The device operates with dual supplies ranging from ±15V to ±15V (total 30V span) and supports a maximum supply voltage difference of 44V. Key electrical parameters include a maximum on-resistance of 100 Ohms, a maximum power dissipation of 200 mW, and a maximum supply current of 2 mA. Switching times are specified at a maximum of 600 ns for turn-on and 450 ns for turn-off. The component functions within an operating temperature range of 0°C to +70°C.
Feature Summary
- High breakdown voltage capability protected up to 44V operating voltage
- Low on-state resistance performance compared to legacy counterparts
- Functionally and pin-to-pin compatible with SILICONIX DG201A
Applications
- Signal routing in TTL or CMOS compatible logic systems
- Audio signal switching applications requiring low distortion
- Data acquisition systems utilizing break-before-make switching
Procurement Notes
Verify component authenticity through authorized Nisshinbo Micro Devices channels. Confirm the specific DMP-16 package variant matches design requirements. Check for RoHS compliance status as indicated in distributor listings. Ensure supply chain stability due to potential end-of-life notifications for related DIP packages.
Selection Notes
Select this component for designs requiring quad SPST switching with high voltage tolerance. Verify input threshold margins relative to V+ supply levels. Consider the 16-DMP package constraints for thermal management given the 200 mW power dissipation limit. Ensure control signals align with TTL or CMOS compatibility specifications.
Part Context
The NJU201A series represents a family of CMOS analog switches designed for general-purpose signal routing. The NJU201AM specifically denotes the surface-mount DMP-16 package variant. This part serves as a modern replacement for older discrete switching solutions, offering integrated quad-channel functionality in a compact form factor suitable for dense PCB layouts.
Replacement Considerations
The NJU201AM is functionally and pin-to-pin compatible with the SILICONIX DG201A. Designers may consider this equivalent for direct board upgrades where original silicon components are unavailable.
