The DDU4C is a 5-tap digital buffered delay line. The input signal is reproduced at the five output terminals T1-T5, shifted in time by an amount determined by the dash number of the device.
The DDU4C series provides a 5‑tap digitally buffered delay line. The input signal is reproduced at five equally spaced outputs (T1‑T5) with a total delay selectable by the dash number. Tap‑to‑tap delay is one‑fifth of the total line delay.
The datasheet lists electrical characteristics such as a 5 V DC supply, 8 ns typical output rise time, operating temperature range 0 °C to 70 °C, and a temperature coefficient of 300 ppm/°C. Application notes cover high‑frequency response, recommended power‑supply bypassing, and test setup procedures.
| Number of taps | 5 |
|---|---|
| Supply voltage | 5 VDC ±5 % |
| Output rise time | 8 ns typical |
| Operating temperature | 0 °C to 70 °C |
| Temp. coefficient of total delay | 300 ppm/°C |
| Minimum input pulse width | 20 % of total delay |
Place a 0.1 µF capacitor from VDD to GND as close as possible to the VDD pin.
The device can accept input pulses as short as 20 % of the total delay.
