16-bit Buffers / Line Drivers with 3-state Outputs
Description
The HD74LVC16244 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 (1
*
to 4
*
). 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.
