3D7428 is a low-noise 8-bit programmable delay line with TTL/CMOS compatible inputs and outputs. It can be programmed via serial or parallel interface, with an increment range of 0.25 to 20.0ns and a delay tolerance of 0.5%.
The Data Delay Devices Series 3D7428 is a versatile 8-bit programmable monolithic delay line designed as an all-silicon, low-power CMOS alternative to hybrid TTL programmable delay lines. The device reproduces the input signal at the output without inversion but shifted in time based on user selection via serial or parallel interfaces.
Available in DIP and SOIC packages, the 3D7428 offers an increment range from 0.25ns through 20.0ns with a delay tolerance of 0.5%. It features both rising- and falling-edge accuracy and is compatible with TTL/CMOS inputs and outputs. The datasheet provides detailed part number specifications, including inherent delays, frequency limits, and pulse width requirements for various models.
