Description
The HD74LVC240A 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. 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.
