FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The 3D7408 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 3D7408 is TTL- and CMOS-

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

both rising- and falling-edge accuracy.

The all-CMOS 3D7408 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.
