FUNCTIONAL DESCRIPTION
The MDU3C-series device is a 3-in-1 digitally buffered delay line. The signal inputs (I1-I3) are reproduced at the outputs (O1-O3), shifted in time by an amount determined by the device dash number (See Table). The delay lines function completely independently of each other.

APPLICATION NOTES
HIGH FREQUENCY RESPONSE
The MDU3C tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 100% of the total delay and periods as small as 200% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data
Delay Devices if your application requires device testing at a specific input condition.
POWER SUPPLY BYPASSING
The MDU3C relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VDD to GND, located as close as possible to the VDD pin, is recommended. A wide VDD trace and a clean ground plane should be used.
