HD74LVC125A Datasheet | Hitachi Semiconductor

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 puter) and low power consumption extends the life of a battery for long time operation.
