FUNCTIONAL DESCRIPTION

The MDU14-series device is a 4-in-1 digitally buffered delay line. The

signal inputs (I1-I4) are reproduced at the outputs (O1-O4), shifted in time

by an amount determined by the device dash number (See Table). The

delay lines function completely independently of each other.
