DESCRIPTION

The DS1007 7-in-1 Silicon Delay Line provides seven independent delay times which are set by Dallas Semiconductor to the customer’s specification. The delay times can be set from 3 ns to 40 ns with an accuracy of ±2 ns at room temperature. The device is offered in both a 16-pin DIP and a 16-pin SOIC. Since the DS1007 is an all-silicon solution, better economy and reliability are achieved when compared to older methods using hybrid technology. The DS1007 reproduces the input logic state at the output after the fixed delay. Dallas Semiconductor can customize standard products to meet special needs.

NOTES: 1. All voltages are referenced to ground. 2. Measured with outputs open. 3. VCC = 5V @25°C. Delays accurate on rising edges within ±2 ns. 4. See Test Conditions below. 5. All output delays in the same speed output tend to vary unidirectionally with temperature or voltage range (i.e., if Out 2 slows down, all other outputs also slow down). 6. Period specifications may be exceeded; however, accuracy will be application-sensitive (decoupling, layout, etc.). 7. tPU = 0 ms for Out 1 through Out 4. TERMINOLOGY Period: The time elapsed between the leading edge of the first pulse and the leading edge of the following pulse. tWI (Pulse Width): The elapsed time on the pulse between the 1.5V point on the leading edge and the 1.5V point on the trailing edge, or the 1.5V point on the trailing edge and the 1.5V point on the leading edge. t RISE (Input Rise Time): The elapsed time between the 20% and the 80% point on the leading edge of the input pulse. tFALL (Input Fall Time): The elapsed time between the 80% and the 20% point on the trailing edge of the input pulse. tPLH (Time Delay, Rising): The elapsed time between the 1.5V point on the leading edge of the input pulse and the 1.5V point on the leading edge of the corresponding output pulse. TEST SETUP DESCRIPTION Figure 3 illustrates the hardware configuration used for measuring the timing parameters on the DS1007. The input waveform is produced by a precision pulse generator under software control. Time delays are measured by a time interval counter (20 ps resolution) connected between the input and each output. Each output is selected and connected to the counter by a VHF switch control unit. All measurements are fully automated, with each instrument controlled by a central computer over an IEEE 488 bus.

INPUT: Ambient Temperature: 25°C ± 3°C Supply Voltage (VCC): 5.0V ± 0.1V Input Pulse: High = 3.0V ± 0.1V Low = 0.0V ± 0.1V Source Impedance: 50 ohm max. Rise and Fall Time: 3.0 ns max. Pulse Width: 500 ns Period: 1 µs OUTPUT: Each output is loaded with the equivalent of one 74F04 input gate. Delay is measured at the 1.5V level on the rising edge. NOTE: Above conditions are for test only and do not restrict the operation of the device under other data sheet conditions.
