SN74LS03NSR Description

Short technical summary and product information.

The SN74LS03NSR from Texas Instruments is a versatile logic gate IC featuring four independent 2-input NAND gates. Each gate has an open-collector output, which requires external pull-up resistors for proper operation. This open-collector design allows for active-low wired-OR or active-high wired-AND functions, making it suitable for bus expansion and level shifting applications.

 

This device operates within a voltage range of 4.75V to 5.25V and offers a maximum propagation delay of 32ns at 5V with a 15pF load capacitance. The operating temperature range is from 0°C to 70°C (TA).

 

The SN74LS03NSR is supplied in a 14-SOIC (Surface Mount) package, with dimensions of 0.209" (5.30mm) width. Its open-collector outputs can be used to generate higher VOH levels, providing flexibility in circuit design. The part is part of the LS (Low-power Schottky) technology family.

 

This component is ideal for digital logic applications requiring NAND functionality with the specific characteristics of open-collector outputs. Its robust design and standard packaging make it a reliable choice for various electronic systems.
