Hex Schmitt-trigger Inverters
REJ03D0218–0100Z
Rev.1.00
Apr.09.2004
Description
The RD74LVC14B 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.
