Overview
The SN74HC02NS is a Texas Instruments logic gate component belonging to the HC series. It contains four independent 2-input positive-NOR gates within a single package. The device operates on a supply voltage range of 2 V to 6 V and features push-pull outputs with a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. Propagation delay is specified at 8 ns. It functions within an operating temperature range of -40°C to +85°C and utilizes a 14-pin SOIC surface-mount package.
Feature Summary
- Contains four independent 2-input NOR logic gates
- Operates across a wide supply voltage range from 2 V to 6 V
- Provides symmetrical push-pull output drive capability
Applications
- Digital signal processing circuits requiring NOR logic functions
- General-purpose logic control systems
- Embedded system interface design
Procurement Notes
Verify the specific suffix 'NS' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with standard SOIC-14 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when a quad 2-input NOR function is required in a compact surface-mount form factor. The HC series offers CMOS performance suitable for general digital applications. Verify that the 8 ns propagation delay meets the timing constraints of the target circuit design.
Part Context
This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC02 designation specifically identifies the quad 2-input NOR gate configuration. The 'N' indicates the PDIP package variant, while 'S' typically denotes the SOIC package; verify the exact package code in the official datasheet to ensure physical compatibility.
Replacement Considerations
Compatible substitutes include other manufacturers' 74HC02 variants or Texas Instruments parts like SN74HC02DR. Ensure pinout compatibility and electrical parameter alignment before substitution.
