FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The 3D7418 Programmable 8-Bit Silicon Delay Line product family
consists of 8-bit, user-programmable CMOS silicon integrated
circuits. Delay values, programmed either via the serial or parallel
interface, can be varied over 255 equal steps ranging from 250ps
to 5.0ns inclusively. Units have a typical inherent (zero step)
delay of 12ns to 17ns (See Table 1). The input is reproduced at
the output without inversion, shifted in time as per user selection.
The 3D7418 is TTL- and CMOS-compatible, capable of driving ten
74LS-type loads, and features both rising- and falling-edge
accuracy.

The all-CMOS 3D7418 integrated circuit has been designed as a reliable, economic alternative to hybrid
TTL programmable delay lines. It is offered in a standard 16-pin auto-insertable DIP and a space saving
surface mount 16-pin SOIC.
