Analog Devices Inc./Maxim Integrated DS1100Z-25

Overview

DS1100Z-25 from Maxim Integrated is a 5-tap silicon delay line delivering precise, equally spaced delays of 5ns, 10ns, 15ns, 20ns, and 25ns at each tap under 5V operation, with ±4ns tolerance over –40°C to +85°C, designed for edge-aligned timing correction in high-speed digital logic interfaces.

For engineers reviewing the DS1100Z-25 datasheet, DS1100Z-25 pinout, DS1100Z-25 application, or DS1100Z-25 equivalent, this device serves as a low-power, TTL/CMOS-compatible timing element where leading- and trailing-edge accuracy, 74LS load drive capability (up to 10 loads per tap), and stable delay performance across temperature and voltage are critical selection criteria.

Technical Context

The DS1100Z-25 implements an all-silicon delay architecture with five fixed, equally spaced taps derived from a monolithic CMOS delay chain. Each tap reproduces both rising and falling edges with matched propagation characteristics, ensuring symmetrical timing alignment without external compensation.

It operates exclusively at 5V (4.75V–5.25V), draws 30–50mA active current, and supports industrial temperature range operation (–40°C to +85°C). Delay tolerances are specified as ±4ns for ≤40ns delays and ±13% for >40ns delays - the DS1100Z-25 falls under the ±4ns category due to its 25ns maximum tap delay.

Key Specifications

FAQ

What is the operating voltage range for DS1100Z-25?

The DS1100Z-25 operates over a supply voltage range of 4.75V to 5.25V, fully compliant with standard 5V TTL/CMOS logic rails. Operation outside this range may cause timing inaccuracy or functional failure. The DS1100Z-25 is not rated for 3.3V or dual-supply operation, and no internal regulation is provided - stable 5V supply with local decoupling is mandatory for specified delay accuracy.

Does DS1100Z-25 support both rising and falling edge delays?

Yes, the DS1100Z-25 guarantees matched tPLH (rising edge) and tPHL (falling edge) delays across all five taps, with identical ±4ns tolerance. This symmetry ensures duty cycle preservation and eliminates pulse distortion - a key differentiator from earlier hybrid delay lines. The DS1100Z-25 achieves this via monolithic CMOS delay chain design, not external compensation.

Can DS1100Z-25 drive modern logic families like 74LVC or 74AHC?

The DS1100Z-25 is specified to drive up to 10 × 74LS loads, which corresponds to ~0.8mA high-level and ~12mA low-level output current. While it can interface with 74LVC or 74AHC inputs (which draw negligible DC current), its output voltage levels (VOH ≥4V, VOL ≤0.5V at 5V) remain compatible. However, capacitive loading beyond 15pF may degrade edge rates - verify signal integrity in target application.

Is DS1100Z-25 pin-compatible with other DS1100 variants?

Yes, all DS1100Z-xxx variants (e.g., DS1100Z-50, DS1100Z-100) share identical 8-pin SO packaging and pinout with DS1100Z-25. Only the nominal delay values differ across taps. No PCB redesign is required when substituting within the DS1100Z family - the DS1100Z-25 can be replaced with another DS1100Z-xxx part using the same footprint and connections.

What is the maximum input frequency supported by DS1100Z-25?

The DS1100Z-25 does not specify a hard maximum input frequency, but AC characterization assumes 1MHz operation. At higher frequencies, active current (ICC) increases, and delay accuracy becomes sensitive to layout, decoupling, and signal edge rates. For reliable operation, input pulse width should exceed 20ns (per datasheet tWI specification), limiting practical use to ≤20MHz periodic signals with clean 3ns max rise/fall times.
