The HD74LVCZ240A has eight inverter drivers with three state outputs in a 20 pin package. This device is an inverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers. When VCC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down. Low voltage and high-speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
