HD74LVC16241 16-bit Buffers / Line Drivers with 3-state Outputs Description The HD74LVC16241 has sixteen buffer drivers with three state outputs in a 48 pin package. This device is a non inverting buffer and has two active low enables (1*, 4*), high enables (2G, 3G). 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.
