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.
