FUNCTIONAL DESCRIPTION
The 3D7608 & 3D7612 devices are versatile 8- & 12-bit
programmable monolithic pulse generators. A rising-edge on the
trigger input (TRIG) initiates the pulse, which is presented on the
output pins (OUT,OUTB). The pulse width, programmed via the
parallel interface, can be varied over 255 (3D7608) or 4095
(3D7612) equal steps according to the formula:
t
PW
= t
inh
+ addr * t
inc
where addr is the programmed address, t
inc
is the pulse width
increment (equal to the device dash number), and t
inh
is the
inherent (address zero) pulse width. The device also offers a reset
input (RES), which can be used to terminate the pulse before the
programmed time has expired.

The all-CMOS 3D7608 & 3D7612 integrated circuits have been designed as reliable, economic alternatives
to hybrid TTL pulse generators. The 3D7608 is offered in a standard 16-pin SOIC, and the 3D7612 is
offered in a standard 20-pin SOL.
