Quad. Bus Buffer Gates with 3-state Outputs
ADE-205-108(Z)
Rev.0
October 1995
Description
The HD74LVC125 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.
