74HC02 SMD IC 7402 H02 SOIC14 74HC02-SOIC-14

Product Overview:

A surface-mount, quad 2-input NOR gate integrated circuit designed for reliable, low-power digital logic operations. Each device contains four independent gates with protective input clamp diodes, enabling the safe use of current-limiting resistors to interface with logic signals that exceed the chip's operating supply voltage.
