J OR W PACKAGE SN7414 . . . 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 (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. 1A 1Y 2A 2Y 3A 3Y GND 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC 6A 6Y 5A 5Y 4A 4Y SN54LS14 . . .
