FUNCTIONAL DESCRIPTION
The 3D7444 device is a small, versatile, quad 4-bit programmable
monolithic delay line. Delay values, programmed via the serial interface,
can be independently varied over 15 equal steps. The step size (in ns) is
determined by the device dash number. Each input is reproduced at the
corresponding output without inversion, shifted in time as per user
selection. For each line, the delay time is given by:
TD
n
= T0 + A
n
* TI

where T0 is the inherent delay, A
n
is the delay address of the n-th line and
TI is the delay increment (dash number). The desired addresses are shifted into the device via the SC and
SI inputs, and the addresses are latched using the AL input. The serial interface can also be used to
enable/disable each delay line. The 3D7444 operates at 5 volts and has a typical T0 of 6ns. The 3D7444 is
CMOS-compatible, capable of sourcing or sinking 4mA loads, and features both rising- and falling-edge
accuracy. The device is offered in a standard 14-pin auto-insertable DIP and a space saving surface mount
14-pin SOIC.
