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:

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.
