Analog Devices Inc./Maxim Integrated DS1100Z-50

Overview

DS1100Z-50 from Maxim Integrated is a 5-tap silicon delay line IC delivering precise, fixed delays of 10ns, 20ns, 30ns, 40ns, and 50ns across equally spaced taps, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 74LS loads per tap - used in digital timing alignment, pulse shaping, and clock deskew in industrial control and test equipment.

For engineers reviewing the DS1100Z-50 datasheet, DS1100Z-50 pinout, DS1100Z-50 application, or DS1100Z-50 equivalent, key selection considerations include tap delay accuracy over temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and leading/trailing edge fidelity for high-fidelity signal delay reproduction.

Technical Context

The DS1100Z-50 implements an all-silicon delay architecture with five discrete, monotonic output taps - each reproducing both rising and falling edges with equal precision and unidirectional delay drift under voltage or temperature variation. Delay values are factory-trimmed and specified as nominal (10/20/30/40/50ns) with absolute tolerances of ±4ns across the full industrial temperature range.

It operates exclusively from a single 5V supply (4.75V–5.25V), draws ≤50mA active current at 1MHz, and features input capacitance of 5–10pF. All outputs are TTL/CMOS-compatible, support vapor-phase, IR, and wave soldering, and meet industrial-grade reliability standards without hybrid construction.

FAQ

What is the nominal delay value for each tap of the DS1100Z-50?

The DS1100Z-50 provides five equally spaced nominal delays: TAP 1 = 10ns, TAP 2 = 20ns, TAP 3 = 30ns, TAP 4 = 40ns, and TAP 5 = 50ns. These values are factory-trimmed and specified at +25°C and 5V, with ±4ns tolerance maintained across the full -40°C to +85°C operating range. Each tap reproduces both leading and trailing edges with identical delay fidelity, as confirmed in the DS1100Z-50 datasheet timing diagrams and AC specifications.

Is the DS1100Z-50 compatible with TTL and CMOS logic families?

Yes, the DS1100Z-50 is fully TTL/CMOS-compatible. Its input accepts standard TTL/CMOS voltage thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V), and its outputs drive 10× 74LS loads while maintaining valid logic levels. The DS1100Z-50 does not require external level-shifting circuitry when interfacing with 5V TTL or CMOS devices, simplifying integration into legacy and mixed-logic systems.

What is the maximum operating temperature range for the DS1100Z-50?

The DS1100Z-50 is rated for continuous operation from -40°C to +85°C, meeting industrial temperature grade requirements. This range is explicitly defined in the Absolute Maximum Ratings and DC/AC Electrical Characteristics sections of the DS1100Z-50 datasheet, and all delay specifications - including ±4ns tolerance - are guaranteed across this full span without derating.

Does the DS1100Z-50 require external passive components for basic operation?

No, the DS1100Z-50 operates as a standalone delay element with no external resistors, capacitors, or crystals required. Only a 0.1μF ceramic decoupling capacitor between VCC and GND is recommended per the DS1100Z-50 application guidance. All timing is internally generated via all-silicon delay circuitry - eliminating tuning components and reducing BOM count.

How does the DS1100Z-50 differ from the older DS1000 series?

The DS1100Z-50 replaces the hybrid DS1000 series with an all-silicon architecture, delivering tighter delay tolerance (±4ns vs. ±10ns), lower power consumption (≤50mA vs. higher ICC), improved thermal stability, and RoHS-compliant SO-8 packaging. As stated in the DS1100Z-50 datasheet, it is an "improved replacement for DS1000", with identical pinout but superior performance and long-term supply assurance.
