Description
The HD74LVC16244A has sixteen line drivers with three state outputs in a 48 pin package. This device is a non
inverting buffer and has two active low enables (1G to 4G). 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.
