FUNCTIONAL DESCRIPTION

The 3D7225 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 0.75ns through 700ns. The

input is reproduced at the outputs without inversion, shifted in time as

per the user-specified dash number. The 3D7225 is TTL- and CMOS-

compatible, capable of driving ten 74LS-type loads, and features both

rising- and falling-edge accuracy.

The all-CMOS 3D7225 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 space saving surface mount

8-pin SOIC and 16-pin SOL packages.
