HD74LVC16540
16-bit Buffers / Line Drivers with 3-state Outputs
ADE-205-057B(Z) Rev.2 September 1995 Description
The HD74LVC16540 has sixteen inverter drivers with three state outputs in a 48 pin package. When G1 and G 2 is low level, this drivers set up output is enable. 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.
Features
