Overview
The NLAST4501DFT is a single-pole double-throw (SPDT) analog switch manufactured by onsemi. It operates on a single supply voltage ranging from 2 V to 5.5 V and supports TTL-compatible logic inputs. The device features low on-resistance of 30 Ω and an off-isolation of 60 dB at 1 MHz. It includes a built-in clamp diode for input protection and offers low power consumption with a maximum quiescent current of 1 μA. The component is housed in a compact SC-70 (SOT-363) surface-mount package, suitable for portable applications.
Feature Summary
- Single SPDT analog switch configuration with TTL-compatible control logic
- Low on-resistance of 30 Ω ensuring minimal signal attenuation
- Built-in input clamp diodes for enhanced overvoltage protection
- Ultra-low static power consumption suitable for battery-operated devices
Applications
- Portable consumer electronics such as mobile phones and MP3 players
- Battery-powered measurement instruments and test equipment
- Signal routing in communication systems requiring level shifting
Procurement Notes
Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels before assembly. Confirm availability through authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single-channel bidirectional analog switch is required within a 2 V to 5.5 V supply range. Consider the 30 Ω on-resistance and 60 dB off-isolation for signal integrity requirements. The SC-70 package is ideal for space-constrained designs compared to larger DIP or SOIC alternatives.
Part Context
This part belongs to the NLAST series of low-voltage analog switches from onsemi. It complements other members like the NLAST4599DFT2, offering similar performance in a single-pole configuration. The series is designed for high-speed switching applications in modern portable electronic devices.
Replacement Considerations
The NLAST4501DFT2G is a verified equivalent part number representing the same device with lead-free packaging confirmation. Verify pinout compatibility and electrical parameters before substitution.
