SN74LS02N

Inverter Gates Overview

The SN74LS02N is a quad 2-input positive-NOR gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS (Low-power Schottky) logic series and operates within a supply voltage range of 4.75V to 5.25V. The device features four independent NOR gates, each with two inputs. It utilizes a 14-pin PDIP package for through-hole mounting. The low-level input voltage is specified at 800mV, while the high-level input voltage threshold is 2V. The operating temperature range extends from 0°C to +70°C.

Inverter Gates Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the component matches the required 74LS logic family specifications and PDIP-14 packaging format. Check for RoHS compliance status if environmental regulations apply to the intended assembly process. Ensure the supplier provides traceable origin data consistent with authorized distribution channels.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR function is required in a digital design. It is suitable for applications needing Low-power Schottky speed and power characteristics. Verify that the 14-pin DIP form factor fits the target PCB layout constraints. Ensure the operating environment remains within the commercial temperature limits of 0°C to +70°C.

Inverter Gates Part Context

This device is part of the widely used 74LS series of logic integrated circuits. It serves as a fundamental building block for implementing complex digital systems. The SN74LS02N provides a reliable solution for NOR logic functions in standard TTL environments. Its compatibility with other 74LS components allows for easy integration into existing designs.

Inverter Gates Replacement Considerations

Compatible substitutes include SN74LS02DR and SN74LS02DRE4. These alternatives offer identical logical functionality but differ in packaging type, utilizing SOIC instead of PDIP.
