SN74LS03N Description

Short technical summary and product information.

The SN74LS03N is a versatile Quad 2-Input NAND Gate integrated circuit manufactured by Texas Instruments. This component belongs to the LS technology family and is designed for applications requiring open-collector outputs, which necessitate external pull-up resistors for proper functionality. It can be used to implement active-low wired-OR or active-high wired-AND functions.

 

The device operates within a voltage range of 4.75V to 5.25V and supports a maximum data rate of 35 Mbps. Its high-speed nature is characterized by a propagation delay of 32ns at 5V and 15pF. The operating temperature range is specified from 0°C to 70°C (TA).

 

Packaged in a 14-pin DIP (Dual In-line Package), the SN74LS03N is suitable for through-hole mounting. The open-collector outputs are capable of sourcing up to 16mA and sinking 250µA. This component is ideal for digital logic designs where flexible output configurations are needed.
