The input (IN) is reproduced at the output (OUT) without inversion, shifted in time as per the user selection. Delay values, programmed either via the serial or parallel interface, can be varied over 255 equal steps according to the formula: Ti,nom = Tinh + i * Tinc where i is the programmed address, Tinc is the delay increment (equal to the device dash number), and Tinh is the inherent (address zero) delay. The device features both rising- and falling-edge accuracy. PIN DESCR...
