The IN Signal Input signal input (IN) is reproduced at the outputs (T1-T8), shifted in time by an T1-T8 Tap Outputs amount determined by the device dash number (See Table). For dash VEE -5 Volts numbers less than 16, the total delay of the line is measured from T1 to GND Ground T8. The nominal tap-to-tap delay increment is given by one-seventh of the total delay, and the inherent delay from IN to T1 is nominally 2.0ns. For dash numbers greater than or equal to 16, the total delay of the line is measured from IN to T8. The nominal tap-to-tap delay increment is given by one-eighth of this number. SERIES SPECIFICATIONS Minimum input pulse width: 40% of total delay Output rise time: 2ns typical Supply voltage: -5VDC ± 5% Power dissipation: 500mw typical (no load) Operating temperature: 0° to 85° C ...
