FUNCTIONAL DESCRIPTION
The 3D7220 10-Tap Delay Line product family consists of fixed-delay
CMOS integrated circuits. Each package contains a single delay line,
tapped and buffered at 10 points spaced uniformly in time. Tap-to-tap
(incremental) delay values can range from 0.75ns through 700ns. The
input is reproduced at the outputs without inversion, shifted in time as
per the user-specified dash number. The 3D7220 is TTL- and CMOS-
compatible, capable of driving ten 74LS-type loads, and features both
rising- and falling-edge accuracy.
The all-CMOS 3D7220 integrated circuit has been designed as a
reliable, economic alternative to hybrid TTL fixed delay lines. It is
offered in a standard 14-pin auto-insertable DIP and space saving
surface mount 14-pin SOIC and 16-pin SOL packages.
