Overview
74ACT16541 16-Bit Buffer/Line Driver with 3-STATE Outputs August 1999 Revised October 1999 74ACT16541 16-Bit Buffer/Line Driver with 3-STATE Outputs General Description The ACT16541 contains sixteen non-inverting buffers with 3-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus oriented transmitter/receiver.
The device is byte controlled.
Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation.

com 74ACT16541 Functional Description The ACT16541 contains sixteen non-inverting buffers with 3-STATE standard outputs.
The device is byte controlled with each byte functioning identically, but independent of the other.
The control pins can be shorted together to obtain full 16-bit operation.
The 3-STATE outputs are controlled by an Output Enable (OEn) input for each byte.
When OEn is LOW, the outputs are in 2-state mode.
When OEn is HIGH, the outputs are in the high impedance mode, but this does not interfere with entering new data into the inputs.
