FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The 3D7622 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:

TRIG Trigger Input

OUTB Complementary

Address Enable Input

t_PW= t_inh+ addr * t_inc

where addr is the programmed address, t_incis the pulse width

increment (equal to the device dash number), and t_inhis 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.

VDD +5 Volts

GND Ground

No Internal Connection

The all-CMOS 3D7622 integrated circuit has been designed as a

reliable, economic alternative to hybrid TTL pulse generators. It is

offered in a standard 14-pin SOIC.
