Operation From Very Slow Edges

Improved Line-Receiving Characteristics

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 (V

T+

) and

negative-going (V

T–

) signals.

These circuits are temperature compensated and

can be triggered from the slowest of input ramps

and still give clean, jitter-free output signals.
