FUNCTIONAL DESCRIPTION
IN
Signal Input
The 3D3418 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 7.5ns inclusively. Units have a typical inherent (address 0)
delay of 20ns (See Table 1). The input is reproduced at the output
without inversion, shifted in time as per user selection. The
3D3418 is CMOS-compatible, and features both rising- and
falling-edge accuracy.

The all-CMOS 3D3418 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.
