DDU4F is a 5-tap digitally buffered delay line produced by Data Delay Devices. This product has five equally spaced outputs and is suitable for standard 14-pin DIP sockets. It has a low profile, is auto-insertable, and has TTL interfaced and buffered inputs and outputs. It also has a 10 T2L fan-out capability.
The document describes the Data Delay Devices DDU4F-series device, which is a 5-tap digitally buffered delay line. The signal input (IN) is reproduced at outputs T1 through T5, shifted in time based on the specific dash number of the part.
This datasheet provides functional descriptions, pin assignments, series specifications including total delay and tap-to-tap increments, absolute maximum ratings, DC electrical characteristics, package dimensions for commercial and military variants, and application notes regarding power supply bypassing and automated testing conditions.
| Total Delay (T1 to T5) | Variable based on dash number, e.g., 4ns for DDU4F-5004 |
|---|---|
| Supply Voltage | 5VDC +/- 5% |
| Operating Temperature | 0° to 70° C |
| Temp. Coefficient of Total Delay | 100 PPM/°C |
| Output Rise Time | 2ns typical |
The inherent delay from IN to T1 is nominally 3.5ns.
Available packages include DIP, Gull-Wing (A2), J-Lead (B2), Military SMD (MC2), and Military DIP.
