Application Information
Power-Supply Decoupling
To achieve the best results when using the DS1123L,
decouple the power supply with a 0.01F and a 0.1F
capacitor. Use high-quality, ceramic, surface-mount
capacitors, and mount the capacitors as close as possi-
ble to the VCC and GND pins of the DS1123L to mini-
mize lead inductance. The DS1123L may not perform as
specified if good decoupling practices are not followed.
Unused Inputs When Using the Serial-
Programming Mode
When using the serial-programming mode, the unused
parallel inputs must be connected to VCC or GND to pre-
vent them from floating and drawing excessive current.
Test Conditions
INPUT:
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:
50
Ω (Max)
Rise and Fall Times:
3.0ns (Max) (Measured
Between 0.6V and 2.4V)
Pulse Width:
500ns
Period:
1s
OUTPUT: The outputs are loaded with a 74F04. Delay
is measured between the 1.5V level of the rising or
falling edge of the input signal and the corresponding
edge of the output signal.
NOTE: Above conditions are for test only and do not
restrict the operation of the device under other data
sheet conditions.

Maximum output frequency depends on the actual step-zero delay value. Worst-case values are shown in the table. Output period
is equal to 2 x tD, where tD = delay value referenced to IN.
