Overview
The NLAS44599MNG is a dual DPDT analog switch IC manufactured by onsemi, housed in a TSSOP-16 surface-mount package. It operates within a supply voltage range of 2 V to 5.5 V and supports an extended temperature range from -55°C to +125°C. Key electrical parameters include a maximum on-resistance of 25 Ohms, a maximum propagation delay of 14 ns, and a maximum power dissipation of 450 mW. The device draws a maximum supply current of 4 uA and features four channels configured as two double-pole double-throw switches.
Feature Summary
- Dual DPDT configuration providing four independent switching channels
- Extended industrial operating temperature range for harsh environments
- Low power consumption with minimal supply current draw
Applications
- Signal routing in portable electronic devices
- Audio signal path switching
- Data acquisition systems requiring low leakage
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notifications or discontinuance notices prior to procurement decisions. Ensure packaging specifications match design requirements.
Selection Notes
Evaluate on-resistance and leakage current against signal integrity requirements. Verify that the TSSOP-16 package dimensions fit the PCB layout constraints. Consider the extended temperature range if the application operates outside standard commercial limits. Compare power dissipation capabilities with thermal management solutions.
Part Context
This component belongs to the NLAS44599 series of analog switches. It is designed for applications requiring multiple single-pole double-throw or double-pole double-throw switching functions in a compact form factor. The series targets consumer electronics and industrial control systems where space and power efficiency are critical.
Replacement Considerations
Check for pin-compatible alternatives within the same family. Verify functional equivalence regarding on-resistance and voltage ratings. Consult official substitution guides for recommended cross-references.
