74ACT16541

16-Bit Buffer/Line Driver with 3-STATE Outputs

Fairchild Semiconductor 

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 (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.
