Overview
HD74LVC14 Hex Schmitt-trigger Inverters ADE-205-064B(Z) Rev.
2 September 1995 Description The HD74LVC14 has six schmitt trigger inverters in a 14 pin package.
Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
