HD74lVC16244A - Hitachi Semiconductor

HD74lVC16244A 16-bit Buffers / Line Drivers with 3-state Outputs

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 (1 G 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 extend.
