SN74LS19AN Description

Short technical summary and product information.

The SN74LS19AN from Texas Instruments is a 6-channel integrated circuit functioning as an inverter with Schmitt-trigger inputs. This design provides different input threshold levels for positive-going and negative-going signals, resulting in excellent noise immunity with a typical hysteresis of 800 millivolts. The circuit is temperature-compensated, allowing it to reliably trigger from slow input ramps and produce clean, jitter-free output signals.

 

This device operates within a voltage range of 4.75V to 5.25V and has a maximum propagation delay of 30ns at 5V and 15pF. It features P-N-P inputs that reduce system loading. The SN74LS19AN is housed in a 14-PDIP package and is designed for through-hole mounting. Its operating temperature range is from 0°C to 70°C.

 

Functionally and mechanically identical to the 'LS13, 'LS14, and 'LS132, the SN74LS19AN offers improved line-receiving characteristics. It is suitable for applications requiring robust signal conditioning and reliable logic level translation in environments with potential noise interference.
