The T1-T5 Tap Outputs signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an VCC +5 Volts amount determined by the device dash number (See Table). For dash GND Ground numbers less than 5025, the total delay of the line is measured from T1 to T5. The nominal tap-to-tap delay increment is given by one-fourth of the total delay, and the inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 5025, the total delay of the line is measured from IN to T5. The nominal tap-to-tap delay increment is given by one-fifth of this number.

Prospect Ave. Clifton, NJ 07013 1 SMD99F APPLICATION NOTES Delay Devices if your application requires device testing at a specific input condition. HIGH FREQUENCY RESPONSE The SMD99F tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data POWER SUPPLY BYPASSING The SMD99F relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended. A wide VCC trace and a clean ground plane should be used.
