1 Operation From Very Slow Edges Improved Line-Receiving Characteristics High Noise Immunity SN5414, SN54LS14, SN5414, SN54LS14...J OR W PACKAGE SN D, N, OR NS PACKAGE SN74LS14... D, DB, OR N PACKAGE (TOP VIEW) 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. 1A 1Y 2A 2Y 3A 3Y GND V CC 6A 6Y 5A 5Y 4A 4Y SN54LS14...
