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:
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 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.
