RD74LVC125B
Quad. Bus Buffer Gates with 3-state Outputs
REJ03D0498–0200
Rev.2.00
Dec. 10, 2004
Description
The RD74LVC125B has four bus buffer gates in a 14 pin package. The device requires the three state control input OE
to be taken high to put the output into the high impedance condition. 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.
