Functional Description

The ACT16244 contains sixteen non-inverting buffers with

3-STATE standard outputs. The device is nibble (4 bits)

controlled with each nibble functioning identically, but inde-

pendent of the other. The control pins can be shorted

together to obtain full 16-bit operation. The 3-STATE out-

impedance mode, but this does not interfere with entering

new data into the inputs.
