FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
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:
TRIG Trigger Input
RES
Reset Input
OUT Pulse Output
OUTB Complementary
Pulse Output
AE
Address Enable Input
P0-P11 Address Inputs
VDD +5 Volts
GND Ground
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.

Do not connect externally
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.
