The width, PWA, depends on the address code (A2-A0) according to the following formula: PWA = PW0 + TINC * A where A is the address code, TINC is the incremental pulse width of the device, and PW0 is the inherent pulse width of the device. The incremental width is specified by the dash number of the device and can range from 0.5ns through 50ns, inclusively. RESET is held LOW during normal operation. When it is brought HIGH, OUT and OUT/ are forced into LOW and HIGH states, respectively, and the unit is ready for the next trigger input. The address is not latched and must remain asserted while the output pulse is active.
