Overview
The NLAS5223BLMNR2G is a dual Single Pole Double Throw (SPDT) analog switch fabricated in sub-micron CMOS technology. It operates on a single supply voltage ranging from 1.65 V to 4.5 V and features an ultra-low on-resistance of 0.35 Ω at VCC = 4.3 V. The device guarantees break-before-make switching, handles full 0-VCC signal ranges, and maintains low standby current below 50 nA. It supports continuous currents up to ±320 mA per switch with large current clamping diodes capable of ±100 mA. The component is housed in a 1.4 x 1.8 mm WQFN10 package.
Feature Summary
- Interfaces directly with 1.8 V chipset logic levels
- Guarantees break-before-make switching to prevent driver shorting
- Supports full 0-VCC signal handling capability
Applications
- Cell phone audio blocks
- Speaker and earphone switching
- Ring-tone chip or amplifier switching
- Modems
Procurement Notes
Verify the specific ordering suffix MNR2G to confirm the WQFN10 package type and tape-and-reel shipping format. Confirm RoHS compliance status as indicated by the product marking. Check for any discontinuation notices or recommended replacement parts via official manufacturer channels before finalizing procurement plans.
Selection Notes
Select this model when interfacing with 1.8 V control logic is required, distinguishing it from the NLAS5223B variant designed for 2.8 V systems. Ensure the application requires dual SPDT switching within the 1.65 V to 4.5 V supply range. Verify that the 1.4 x 1.8 mm footprint fits the design constraints.
Part Context
This component belongs to the NLAS5223 series of ultra-low resistance analog switches. The 'L' suffix specifically denotes the version optimized for 1.8 V chipset interfaces, whereas the standard 'NLAS5223B' targets 2.8 V applications. Both share identical analog performance characteristics but differ in digital input threshold voltages.
Replacement Considerations
The NLAS5223BMNR2G serves as a functional alternative if 2.8 V interface compatibility is acceptable instead of 1.8 V. The NLAS5223BMUR2G offers the same electrical specifications but utilizes a UQFN10 package instead of WQFN10.
