HD74LS04P (74LS04) Logic chip
This content will be shared across all product pages.
Description:
The HD74LS04P is a high-speed, low-power Hex Inverter integrated circuit. It features six independent inverters, each with a single input and output. The inverter performs the Boolean function Y = NOT A (Y = A') where A is the input and Y is the output. This IC is widely used in digital electronics for signal inversion and logic level shifting applications.
