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