SN74LS14DR Description

Short technical summary and product information.

The SN74LS14DR from Texas Instruments is a versatile logic gate IC featuring six independent inverters, each equipped with Schmitt-Trigger inputs. This design allows for clean, jitter-free output signals even with slow input ramps, providing high noise immunity.

 

The device operates within a voltage range of 4.75V to 5.25V, making it suitable for various digital applications. It is packaged in a standard 14-pin SOIC (Small Outline Integrated Circuit) package, designed for surface mounting.

 

Key electrical characteristics include a maximum propagation delay of 22ns at 5V and 15pF, and it draws a quiescent current of 400µA, with a maximum current of 8mA. The operating temperature range is from 0°C to 70°C.

 

This component is ideal for signal conditioning, debouncing switches, and other digital logic functions where reliable signal transition is critical. Its Schmitt-Trigger capability ensures robust performance in noisy environments.
