4–in–1 High–Speed Silicon Delay Line

Dallas Semiconductor -> Maxim Integrated 

DS1044

TEST CONDITIONS

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: 50Ω Max.

Rise and Fall Time: 3.0 ns Max. – Measured between 0.6V and 2.4V.

Pulse Width: 500 ns

Pulse Period: 1 µs

Output Load Capacitance: 15 pF

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.

Note: The above conditions are for test only and do not restrict the devices under other data sheet conditions.

NOTES:

1. All voltages are referenced to ground.

2. @ VCC=5 volts and 25°C, delay accuracy on both the rising and falling edges within tolerances given in

Table 1.

3. Pulse width and duty cycle specifications may be exceeded, however, accuracy will be application sensitive

with respect to de–coupling, layout, etc.
