74ABT16244
16-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT16244 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is nibble controlled. Individual 3-
STATE control inputs can be shorted together for 8-bit or
16-bit operation.
