The signal inputs (I1-I2) are reproduced at the outputs (O1-O2), shifted in time by an amount determined by the device dash number (See Table). The delay lines function completely independently of each other.

Prospect Ave. Clifton, NJ 07013 1 MDU12H APPLICATION NOTES Delay Devices if your application requires device testing at a specific input condition. HIGH FREQUENCY RESPONSE The MDU12H 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 50% of the total delay and periods as small as 100% 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 POWER SUPPLY BYPASSING The MDU12H relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VEE to GND, located as close as possible to the VEE pin, is recommended. A wide VEE trace and a clean ground plane should be used.
