| SN54AHC14, SN74AHC14 HEX SCHMITT-TRIGGER INVERTERS SCLS238F - OCTOBER 1995 - REVISED JANUARY 2000 D D D D D description The 'AHC14 devices contain six independent inverters. These devices perform the Boolean function Y = A. Each circuit functions as an independent inverter, but because of the Schmitt action, the inverters have different input threshold levels for positive-going (VT+) and negative-going (VT-) signals. The SN54AHC14 is characterized for operation over the full military temperature range of -55C to 125C. The SN74AHC14 is characterized for operation from -40C to 85C.
