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 con-
trolled by an Output Enable (OE
