PCB Layout description/ordering information
The ’ACT563 devices are octal D-type transparent latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs are set to the plements of the data (D) inputs. When LE is taken low, the Q outputs are latched at the inverse logic levels set up at the D inputs.
