Overview
The NL17SZ27DBVT1G is a single 3-input NOR gate from the onsemi NL17SZ series, designed for operation within a 1.65 V to 5.5 V supply voltage range. It features inputs and outputs that are overvoltage tolerant up to 5.5 V, ensuring compatibility with various logic levels. The device exhibits a typical propagation delay of 2.6 ns at 5 V. Packaged in a compact SC-74A-5 (X2SON) surface-mount format, it supports industrial temperature ranges from -55°C to +125°C.
Feature Summary
- Single 3-input NOR logic function
- Wide operating voltage range from 1.65 V to 5.5 V
- Overvoltage tolerant I/Os up to 5.5 V
- Compact SC-74A-5 surface-mount package
Applications
- Portable consumer electronics requiring low voltage operation
- Battery-powered devices needing extended runtime
- Industrial control systems operating in harsh environments
- Communication equipment interface circuits
Procurement Notes
Verify the complete part number including suffixes such as DBVT1G to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure ESD handling procedures are followed during storage and assembly due to the small form factor.
Selection Notes
Select this component when a 3-input NOR function is required in space-constrained designs. It is suitable for applications transitioning between different voltage domains due to its overvoltage tolerance. Consider the SC-74A-5 package dimensions for PCB layout constraints and verify thermal performance for high-temperature industrial applications.
Part Context
This part belongs to the NL17SZ family of ultra-low voltage logic gates. The series focuses on minimizing power consumption while maintaining speed in portable applications. The NL17SZ27 specifically provides three-input logic capability, distinguishing it from standard two-input variants within the same technology node.
Replacement Considerations
Check for direct pin-compatible alternatives within the NL17SZ series or other manufacturers' low-voltage 3-input NOR gates. Verify that substitute components match the 1.65 V to 5.5 V operating range and SC-74A-5 package footprint. Ensure equivalent propagation delay and overvoltage tolerance specifications.
