Omni Pro Electronics announced its release of the new 4- and 8-bit monolithic programmable delay lines from data delay devices. These digitally programmable lines are used in medical imaging, industrial, aerospace and other timing-critical applications. Omni Pro offers the 8-bit lines with step sizes ranging from 50 ps through 20 ns, and a quad 4-bit line with step sizes from 1 ns through 400 ns. These devices use all-Si, CMOS technology and are vapor-phase, IR and wave solderable. Temperature stability is typically ±1.5 percent (-40°C to 85°C).

The 4-bit 3D3424 and 3D7424 devices have four independent programmable lines on one chip and have a low quiescent current (5 mA typical). They also both have delay tolerance of 3 percent or 2 ns, line-to-line matching of 1 percent or 1 ns typical and a minimum input pulse width of 10 percent of total delay. The 3D3424 has is available in steps sizes of 1 ns through 300 ns and has a Vdd stability of ±0.5 percent typical (3.0 V to 3.6 V), while the 3D7424 step size range is 0.75 ns through 400 ns with a typical Vdd stability of ±0.5 percent (4.75 V to 5.25 V).

The 8-bit 3D3428, 3D3438, 3D7428 and 3D7438 are programmable via serial or parallel interface and have a delay tolerance of 0.5 percent and typical supply currents of 2 or 3 mA. The 3D3428 and 3D3438 have 3.3 V CMOS compatible inputs and outputs while the other two have TTL/CMOS compatible inputs and outputs.
