Analog Devices Inc./Maxim Integrated DS1100Z-20+

Overview

DS1100Z-20+ from Maxim Integrated is a 5-tap silicon delay line IC delivering fixed, equally spaced delays of 4ns, 8ns, 12ns, 16ns, and 20ns at each tap. It operates at 5V, supports industrial temperature range (−40°C to +85°C), drives up to 10 LS-TTL loads per tap, and reproduces both leading and trailing edges with ±4ns tolerance over full temperature range. It is used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100Z-20+ datasheet, DS1100Z-20+ pinout, DS1100Z-20+ application, or DS1100Z-20+ equivalent, key selection criteria include tap delay precision, edge fidelity across temperature, TTL/CMOS compatibility, SO-8 package footprint, and industrial-grade reliability for embedded control and test instrumentation.

Technical Context

The DS1100Z-20+ implements an all-silicon delay architecture with five discrete, monotonic output taps-no external components required. Each tap provides deterministic propagation delay referenced to the same input edge, with unidirectional drift under voltage or temperature variation (e.g., if TAP1 slows, all taps slow proportionally).

It uses CMOS logic-level inputs and outputs, features 5V-only operation, and maintains stable delay accuracy without trimming or calibration. Input-to-output timing is measured at the 1.5V threshold, and power-up time is guaranteed ≤200μs.

Key Specifications

Pinout & Package

DS1100Z-20+ is housed in an 8-pin SOIC (150-mil) package with industry-standard footprint (outline no. 21-0041, land pattern 90-0096). RoHS-compliant lead-free finish denoted by "+" suffix.

FAQ

What is the maximum operating temperature range for DS1100Z-20+?

The DS1100Z-20+ is rated for continuous operation from −40°C to +85°C. This industrial temperature range is confirmed in the Absolute Maximum Ratings and DC/AC Electrical Characteristics tables, and applies across all five taps and under full supply voltage tolerance (4.75V to 5.25V). The device maintains its ±4ns delay tolerance specification across this entire range.

Does DS1100Z-20+ support both rising and falling edge delays?

Yes, DS1100Z-20+ reproduces both leading and trailing edges with equal precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) are specified identically in the AC Electrical Characteristics table, with the same ±4ns tolerance over −40°C to +85°C. This symmetry ensures accurate pulse-width preservation in timing-critical applications.

Can DS1100Z-20+ drive standard TTL logic directly?

Yes, DS1100Z-20+ can drive up to 10 LS-TTL loads per tap, as explicitly stated in the General Description. Its output drive strength (IOL = 12mA, IOH = −1mA) and voltage thresholds (VIH ≥2.2V, VIL ≤0.8V) meet LS-TTL interface requirements without external buffers or level shifters.

Is DS1100Z-20+ pin-compatible with other DS1100 variants like DS1100Z-50+?

Yes, all DS1100Z-xxx+ variants share the same 8-pin SOIC package and identical pinout - VCC, TAP1–TAP5, IN, and GND occupy identical positions regardless of nominal delay value. This allows drop-in replacement within the same package family when delay requirements change, provided board layout accommodates the same SO-8 footprint.

What does the "+" suffix in DS1100Z-20+ indicate?

The "+" suffix in DS1100Z-20+ denotes a lead(Pb)-free and RoHS-compliant package, as confirmed in the Ordering Information and Package Information sections. It specifies that the device uses matte tin plating and meets JEDEC J-STD-020 reflow profile requirements for lead-free assembly (peak temperature +260°C).
