DESCRIPTION

The DS1135L series is a low-power, 3V high-speed version of the popular DS1013, DS1033, and

DS1035 series.

The DS1135L series of delay lines have three independent logic buffered delays in a single package. The

device is our fastest 3-in-1 delay line. It is available in a 150-mil 8-pin SO.

The device features precise leading and trailing edge accuracy. It has the inherent reliability of an all-

silicon delay line solution.

Standard delay values are indicated in Table 1.

DS1135L TEST CONDITIONS Ambient Temperature: 25°C ± 3°C Supply Voltage (VCC ): 3.3V ± 0.1V Input Pulse: High: 3.0V ± 0.1V Low: 0.0V ± 0.1V Source Impedance: 50Ω Max. Rise and Fall Time: 3.0ns Max. — Measured between 0.6V and 2.4V. Pulse Width: 500ns Pulse Period: 1µs Output Load Capacitance: 15pF Output: Each output is loaded with the equivalent of one 74F04 input gate. Data is measured at the 1.5V level on the rising and falling edges.
