3D7225 Monolithic 5-Tap Silicon Delay Line 3D7225 replaces obsolete Maxim DS1000 series Silicon Delay Line Description: Features: The 3D7225 5-Tap Delay Line product family consists of fixeddelay CMOS integrated circuits. Each package contains a single delay line, tapped and buffered at 5 points spaced uniformly in time. Tap-to-tap (incremental) delay values can range from ± 0.75ns through 700ns. The input is reproduced at the outputs without inversion, shifted in time as per the user-specified dash number. The 3D7225 is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads, and features both rising- and fallingedge accuracy. All-silicon, low-power CMOS technology TTL/CMOS compatible inputs and outputs Low ground bounce noise Leading- and trailing-edge accuracy Delay range: 0.75ns through 3500ns Delay tolerance: 2% or 0.5ns Temperature stability: ±2% typical VDD stability: ±1% typical (4.75V-5.25V) Minimum input pulse width: 30% of total delay The all-CMOS 3D7225 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL fixed delay lines. It is available in bare die and wafer format for maximum integration and size reduction in today’s complex hybrid circuit and MultiChip-Module applications.
