FUNCTIONAL DESCRIPTION
The 3D7205 5-Tap Delay Line product family consists of fixed-delay
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 8.0ns through 100ns. The
input is reproduced at the outputs without inversion, shifted in time as
per the user-specified dash number. The 3D7205 is TTL- and CMOS-
compatible, capable of driving ten 74LS-type loads, and features both
rising- and falling-edge accuracy.

The all-CMOS 3D7205 integrated circuit has been designed as a
reliable, economic alternative to hybrid TTL fixed delay lines. It is offered in a standard 8-pin auto-
insertable DIP and a space saving surface mount 8-pin SOIC.
