Functional Description
The ACTQ16541 contains sixteen non-inverting buffers
with 3-STATE standard outputs. The device is byte con-
trolled with each byte functioning identically, but indepen-
dent 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.
