Description
The HD74LVC125A has four bus buffer gates in a 14 pin package. The device require the three state control input C to
be taken high to put the output into the high impedance condition, whereas the device requires the control input to be
low to put the output into high impedance. 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.
