Analog Devices Inc./Maxim Integrated DS1100Z-75+T&R

Overview

DS1100Z-75+T&R from Maxim Integrated is a 5-tap silicon delay line IC providing fixed, equally spaced delays of 15ns, 30ns, 45ns, 60ns, and 75ns at each tap, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads per output-used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100Z-75+T&R datasheet, DS1100Z-75+T&R pinout, DS1100Z-75+T&R application, or DS1100Z-75+T&R equivalent, key selection considerations include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and industrial-grade reliability without hybrid construction.

Technical Context

The DS1100Z-75+T&R implements an all-silicon delay architecture with five discrete, fixed-delay outputs referenced to a single input signal; each tap reproduces both leading and trailing edges with equal accuracy, and delay variation is unidirectional across temperature and supply voltage changes.

It operates strictly at 5V (4.75V–5.25V), supports 1MHz input frequency, exhibits 5pF typical input capacitance, and maintains stable delay performance under vapor-phase, IR, and wave soldering-enabling direct integration into high-reliability industrial PCB assemblies without reflow concerns.

FAQ

What is the nominal delay value for each tap of the DS1100Z-75+T&R?

The DS1100Z-75+T&R provides five equally spaced nominal delays: TAP 1 = 15ns, TAP 2 = 30ns, TAP 3 = 45ns, TAP 4 = 60ns, and TAP 5 = 75ns. These values are specified at +25°C and 5V, with tolerances tightened to ±4ns for delays ≤40ns and ±13% for delays >40ns across the full -40°C to +85°C range. DS1100Z-75+T&R maintains unidirectional delay drift-ensuring consistent relative spacing between taps under varying conditions.

Is DS1100Z-75+T&R compatible with TTL and CMOS logic families?

Yes, DS1100Z-75+T&R features TTL/CMOS-compatible inputs and outputs, with VIH ≥2.2V, VIL ≤0.8V, and output drive capability of ≥12mA low-level and ≥1mA high-level current-sufficient to directly drive 10 LS-TTL loads per tap. Its 5V operation and 5pF input capacitance ensure seamless interfacing with 74LS, 74F, and standard CMOS families without level shifters. DS1100Z-75+T&R meets these specifications across its full industrial temperature range.

What package type and RoHS status does DS1100Z-75+T&R use?

DS1100Z-75+T&R uses an 8-pin SOIC (150-mil) package with lead(Pb)-free, RoHS-compliant construction indicated by the "+" suffix. It conforms to JEDEC MS-012 standards, supports vapor-phase, IR, and wave soldering, and has a maximum lead temperature of +260°C for lead-free reflow. The "T&R" designation confirms tape-and-reel packaging for automated SMT placement. DS1100Z-75+T&R's land pattern is documented as outline 21-0041 and footprint 90-0096.

Does DS1100Z-75+T&R support both rising and falling edge delays with equal accuracy?

Yes, DS1100Z-75+T&R is explicitly designed to reproduce both leading and trailing edges with equal precision-verified by tPLH and tPHL measurements at the 1.5V logic threshold. Initial delay tolerances apply identically to both edge types at +25°C, and temperature/voltage-induced variations affect rising and falling delays in parallel. This dual-edge fidelity makes DS1100Z-75+T&R suitable for pulse-width preservation and glitch filtering applications where duty cycle integrity is critical.

Can DS1100Z-75+T&R replace older DS1000-series hybrid delay lines?

Yes, DS1100Z-75+T&R is positioned as an improved replacement for DS1000-series hybrid delay lines, offering tighter delay tolerance (±4ns vs ±10%), lower power (30–50mA vs >100mA), all-silicon reliability, and full reflow compatibility. While not pin-compatible due to differing pinouts (DS1000 used 14-pin DIP), DS1100Z-75+T&R delivers superior edge matching and unidirectional delay drift. DS1100Z-75+T&R requires board layout revision but provides measurable performance and manufacturability gains in new designs.
