The 3D3622 device is a versatile 22-bit programmable monolithic pulse generator. 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 serial interface, can be varied over 4,194,303 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 3D3622 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL pulse generators. It is offered in a standard 14-pin SOIC.
