Overview
The NJU211D is a quad single-pole single-throw (SPST) analog switch manufactured by Nisshinbo Micro Devices Inc. in a 16-DIP package. It features four independent channels with normally closed logic, operating on dual supplies up to ±15V. Key electrical parameters include a maximum on-resistance of 175 ohms, channel-to-channel matching of negative values, and a maximum charge injection of 20pC. The device exhibits a maximum turn-on time of 1µs and turn-off time of 500ns, with an off-state leakage current of 5nA. It provides -90dB crosstalk at 100kHz and operates within a temperature range of 0°C to 70°C.
Feature Summary
- Four independent SPST analog switching channels integrated into a single component
- Normally closed logic configuration for signal path management
- Low charge injection characteristics suitable for precision signal routing
- High isolation performance with low off-state leakage current
Applications
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio signal routing and switching applications
- Instrumentation front-end signal selection
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's official documentation before procurement. Confirm that the component meets the required environmental specifications for the intended operating temperature range. Check for any end-of-life or not recommended for new design status updates from the supplier.
Selection Notes
Select this component when a quad SPST switch with normally closed functionality is required. Ensure the system voltage does not exceed the ±15V dual supply limit. Consider the 175 ohm on-resistance and 500ns turn-off time for high-speed signal integrity requirements. Verify that the 16-DIP through-hole package fits the target PCB layout constraints.
Part Context
The NJU211D belongs to the family of analog switches produced by Nisshinbo Micro Devices Inc., formerly New Japan Radio Co., Ltd. This series focuses on providing reliable signal routing solutions for general-purpose electronic equipment. The component utilizes standard bipolar technology to achieve consistent switching performance across multiple channels.
Replacement Considerations
Consult the manufacturer's official cross-reference list for verified substitute part numbers. Ensure any replacement maintains the same 16-DIP package and normally closed logic configuration. Verify that the alternative component meets or exceeds the original electrical specifications for resistance, speed, and voltage ratings.
