... Octal Buffers / Line Drivers with 3-state Outputs Description The HD74LVC244A has eight line drivers with three state outputs pin package. This device is a non 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 ...
