FUNCTIONAL DESCRIPTION

The MDU28C-series device is a 2-in-1 digitally buffered delay line. The

signal inputs (I1-I2) are reproduced at the outputs (O1-O2), shifted in time

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

delay lines function completely independently of each other.
