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: tPW = tinh + addr * tinc where addr is the programmed address, tinc is the pulse width increment (equal to the device dash number), and tinh 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.
