Analog Devices Inc./Maxim Integrated DS1100Z-200/T&R

Overview

DS1100Z-200/T&R from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced delays of 40ns, 80ns, 120ns, 160ns, and 200ns at each tap under 5V operation, with ±4ns tolerance over -40°C to +85°C, used for digital signal alignment in test equipment and timing-critical logic interfaces.

For engineers reviewing the DS1100Z-200/T&R datasheet, DS1100Z-200/T&R pinout, DS1100Z-200/T&R application, or DS1100Z-200/T&R equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, SO-8 package footprint, 5V supply requirement, and ability to drive up to 10 × 74LS loads per output.

Technical Context

The DS1100Z-200/T&R implements an all-silicon delay architecture with fixed propagation paths-no PLLs, oscillators, or programmable logic-ensuring deterministic, edge-aligned delays for both rising and falling input transitions. Each of the five taps reproduces the input logic state after its nominal delay with matched tPLH/tPHL characteristics.

It operates exclusively at 5V (4.75V–5.25V), supports standard logic-level inputs (VIH ≥ 2.2V, VIL ≤ 0.8V), and delivers outputs compatible with TTL and CMOS families. Power-up time is 200μs, and input pulse width must exceed 20% of Tap 5 delay (i.e., ≥40ns) for guaranteed timing integrity.

Key Specifications

FAQ

What is the operating temperature range for DS1100Z-200/T&R?

The DS1100Z-200/T&R is rated for continuous operation from -40°C to +85°C. All delay specifications-including ±4ns tolerance for Tap 1 and ±13% for Tap 5-are guaranteed across this full industrial temperature range when supplied with 4.75V–5.25V. This makes DS1100Z-200/T&R suitable for deployment in harsh environments such as factory automation and outdoor test instrumentation.

Does DS1100Z-200/T&R require external configuration or programming?

No, DS1100Z-200/T&R is a fully static, unprogrammable delay line. Its five tap delays (40ns, 80ns, 120ns, 160ns, 200ns) are hardwired in silicon and require no initialization, clock, or serial interface. Once powered with 5V, DS1100Z-200/T&R immediately begins reproducing the input signal at each tap with fixed latency-ideal for deterministic, zero-latency-config systems.

Can DS1100Z-200/T&R drive standard TTL logic directly?

Yes, DS1100Z-200/T&R can directly drive up to 10 × 74LS loads per tap, meeting TTL voltage thresholds (VOH ≥ 2.4V, VOL ≤ 0.4V) and current requirements. Its -1mA/12mA drive strength and TTL/CMOS-compatible input ensure seamless interfacing with legacy and modern logic families without level shifters or buffers-simplifying board design and reducing BOM count.

What is the meaning of "/T&R" in DS1100Z-200/T&R?

The "/T&R" suffix in DS1100Z-200/T&R indicates tape-and-reel packaging-a standard format for automated SMT placement. The device is supplied in a moisture-sensitive SO-8 carrier tape, conforming to EIA-481 standards, with 2,500 units per reel. This packaging ensures consistent feeding into pick-and-place machines and supports high-yield, high-volume manufacturing of DS1100Z-200/T&R-based assemblies.

How does DS1100Z-200/T&R handle input pulse width and frequency limits?

DS1100Z-200/T&R requires minimum input pulse width of 20% of Tap 5 delay (i.e., ≥40ns) and supports input periods down to 1μs (1MHz). At higher frequencies, active current (ICC) increases beyond the typical 50mA spec, and delay accuracy may degrade due to layout-dependent factors like decoupling and trace impedance-so DS1100Z-200/T&R should be used within datasheet-specified AC conditions for guaranteed timing behavior.
