The width, PWA, depends on the address code (A11-A0) according to the following formula: PWA = PW0 + TINC * A PIN DESCRIPTIONS TRIG Trigger Input OUT Non-inverted Output OUT/ Inverted Output A0-A11 Address Bits RES Reset VCC +5 Volts GND Ground 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 400ns, inclusively. RESET is held LOW during normal operation. When it is brought HIGH, OUT and OUT/ are f...
