FUNCTIONAL DESCRIPTION

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:

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.
