FUNCTIONAL DESCRIPTION

The 3D7215 5-Tap Delay Line product family consists of fixed-delay 5V
CMOS integrated circuits. Each package contains a single delay line,
tapped and buffered at 5 points spaced uniformly in time. Tap-to-tap
(incremental) delay values can range from 1ns through 50ns. The input
is reproduced at the outputs without inversion, shifted in time as per the
user-specified dash number. The 3D7215 is 5V CMOS-compatible and
features both rising- and falling-edge accuracy.

The all-CMOS 3D7215 integrated circuit has been designed as a
reliable, economic alternative to hybrid fixed delay lines. It is offered in
a standard 8-pin auto-insertable DIP and a space saving surface mount 8-pin SOIC.
