Analog Devices Inc./Maxim Integrated DS1100Z-30

Overview

DS1100Z-30 from Maxim Integrated is a 5-tap silicon delay line IC delivering precise, fixed delays of 6ns (TAP1), 12ns (TAP2), 18ns (TAP3), 24ns (TAP4), and 30ns (TAP5) with ±4ns tolerance over -40°C to +85°C. It operates at 5V, reproduces both leading and trailing edges with equal accuracy, and drives up to 10 74LS loads per tap. It is used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100Z-30 datasheet, DS1100Z-30 pinout, DS1100Z-30 application, or DS1100Z-30 equivalent, key selection considerations include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and edge-fidelity for high-speed logic synchronization.

Technical Context

The DS1100Z-30 implements an all-silicon delay architecture with five equally spaced taps derived from a monolithic CMOS timing circuit. Delay values are factory-trimmed and specified at 1.5V switching threshold for both tPLH and tPHL, ensuring matched rising/falling edge propagation.

It functions as a passive, non-retriggerable delay element - input pulses propagate through fixed internal delay paths without buffering or regeneration. Each tap output is electrically isolated and capable of driving standard TTL/CMOS loads under 5V supply, with active current draw ≤50mA typical at 1MHz.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and timing solutions for industrial, automotive, and communications systems.

The DS1100 series was developed as a silicon-based replacement for hybrid delay lines, targeting applications needing repeatable, temperature-stable fixed delays without microcontroller-based calibration.

FAQ

What is the nominal delay value for each tap of the DS1100Z-30?

The DS1100Z-30 provides five equally spaced delays: TAP1 = 6ns, TAP2 = 12ns, TAP3 = 18ns, TAP4 = 24ns, and TAP5 = 30ns, all referenced to the 1.5V switching threshold under 5V supply and -40°C to +85°C operation. These values are factory-trimmed and guaranteed per the datasheet's Table 1.

Does the DS1100Z-30 support both rising and falling edge delays with equal accuracy?

Yes, the DS1100Z-30 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH and tPHL delays are matched within ±4ns over the full industrial temperature range, ensuring pulse-width integrity for applications like clock/data deskew and pulse shaping.

What is the maximum capacitive load the DS1100Z-30 can drive per tap?

The DS1100Z-30 is rated to drive up to 10 standard 74LS logic inputs per tap, corresponding to approximately 10 × 20pF = 200pF total load capacitance. Driving heavier loads may degrade delay accuracy and edge fidelity; external buffer stages are recommended beyond this limit.

Is the DS1100Z-30 RoHS-compliant and lead(Pb)-free?

Yes, the DS1100Z-30 carries the "+" suffix in its ordering code (e.g., DS1100Z-30+) to indicate RoHS compliance and lead(Pb)-free packaging. The SO-8 package meets JEDEC J-STD-020 reflow profiles, with peak soldering temperature up to +260°C for lead-free processes.

Can the DS1100Z-30 be used in place of the older DS1000 series?

Yes, the DS1100Z-30 is positioned as an improved replacement for the DS1000 series, offering superior delay stability, tighter tolerance (±4ns vs. ±10ns), all-silicon reliability, and broader temperature support. Pinout and voltage compatibility are maintained, but layout review is advised due to differences in decoupling and noise sensitivity.
