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.
