HD74LS02P (74LS02) Logic chip
This content will be shared across all product pages.
Description:
The HD74LS02P is a quad 2-input NOR gate integrated circuit, designed to perform logical NOR operations on two inputs. Each gate within the IC has two inputs (A and B) and one output (Y), where the output is low (logic 0) only when both inputs are high (logic 1). This IC is widely used in digital electronics for various logic operations, including signal inversion, logic gates, and combinational logic circuits.
