The DS1135 series of delay lines have three independent logic buffered delays in a single package. The device is Dallas Semiconductor's fastest 3-in-1 delay line. It is available in a standard 8-pin DIP and 150-mil 8-pin Mini-SOIC, as well as an 8-pin, 118-mil SOP. The device features precise leading and trailing edge accuracy. It has the inherent reliability of an allsilicon delay line solution. Each output is capable of driving up to 10 LS loads. Standard delay values are indicated in Table 1.

TEST SETUP DESCRIPTION Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1135. The input waveform is produced by a precision pulse generator under software control. Time delays are measured by a time interval counter (20ps resolution ) connected to the output. The DS1135 output taps are selected and connected to the interval counter by a VHF switch control unit. All measurements are fully automated with each instrument controlled by the computer over an IEEE 488 bus. 2 of 6 DS1135 DS1135 TEST CIRCUIT Figure 2 PULSE GENERATOR START 3 IN TIME INTERVAL COUNTER 50W STOP VHF SWITCH CONTROL UNIT UNIT UNDER TEST OUT 50W TAPS 1-3 3 of 6 DS1135 ABSOLUTE MAXIMUM RATINGS* Voltage on Any Pin Relative to Ground Operating Temperature Storage Temperature Soldering Temperature Short Circuit Output Current -1.0V to +7.0V -40C to +85C -55C to +125C See J-STD-020A specification 50mA for 1 second * This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied.
