SN74LS02D

Inverter Gates Overview

The SN74LS02D is a quad 2-input positive-NOR gate manufactured by Texas Instruments, not onsemi. It belongs to the 74LS logic family and utilizes bipolar technology. The device features four independent NOR gates within a single package. It operates with a supply voltage range of 4.75V to 5.25V. The maximum output low current (IOL) is 16 mA, while the maximum output high current (IOH) is -0.4 mA. Propagation delay ranges from 10 ns to 50 ns. The component supports a data rate up to 35 Mbps. It is housed in a 14-pin SOIC package and functions within an operating temperature range of 0°C to 70°C.

Inverter Gates Procurement Notes

Verify manufacturer identity carefully as the part number prefix SN indicates Texas Instruments production, despite the requested brand being onsemi. Confirm the suffix D corresponds to the specific SOIC-14 package variant. Ensure the order matches the exact logical function and pinout requirements for your circuit design before purchasing.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR gate is required within a system utilizing standard 5V TTL logic levels. Consider the propagation delay specifications if timing constraints are critical. Verify that the 16 mA output drive capability meets the load requirements of the connected inputs in the target application.

Inverter Gates Part Context

This component is part of the broader 74LS series of integrated circuits, which are widely used in digital electronics. The 74LS02 specifically provides NOR functionality, contrasting with other common gates like NAND or AND. It serves as a fundamental building block for complex combinational logic designs in industrial and consumer electronic devices.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74HC02 for CMOS performance upgrades and the MM74HC02. Other equivalents within the same logic family may also be suitable depending on specific speed and power consumption requirements.
