Description
SN74LS03N Quad 2-Input NAND Gate IC with Open-Collector Outputs – DIP-14 (74LS Series Logic)
The SN74LS03N is a TTL logic IC that contains four independent 2-input NAND gates with open-collector outputs. Each gate performs the NAND logic function and allows for wired-AND connections by externally connecting outputs together (with pull-up resistors).It is housed in a standard DIP-14 through-hole package and is ideal for digital logic systems, relay drivers, and applications requiring level shifting or external pull-up control.
