SN74LS14 Datasheet, PDF (1/22 Pages) Texas Instruments – HEX SCHMITT-TRIGGER INVERTERS
D Operation From Very Slow Edges
D Improved Line-Receiving Characteristics
D High Noise Immunity
description
Each circuit functions as an inverter, but because
of the Schmitt action, it has different input
threshold levels for positive-going (VT+) and
negative-going (VT–) signals.
These circuits are temperature compensated and
can be triggered from the slowest of input ramps
and still give clean, jitter-free output signals.
