SN74LS14D Description

Short technical summary and product information.

The SN74LS14D from Texas Instruments is a hex inverter integrated circuit that utilizes Schmitt-Trigger inputs. This design provides different input threshold levels for positive-going and negative-going signals, offering high noise immunity and the ability to trigger from slow input ramps, resulting in clean, jitter-free output signals.

 

This device operates with a supply voltage range of 4.75V to 5.25V and features 6 independent inverter circuits. Each circuit has a single input and a single output. The maximum propagation delay is specified at 22ns at 5V with a 15pF load capacitance. The input logic level is typically 1.9V.

 

The SN74LS14D is available in a 14-SOIC surface mount package. Its operating temperature range is from 0°C to 70°C, making it suitable for various industrial and commercial applications requiring reliable signal conditioning and logic inversion.
