Analog Devices Inc./Maxim Integrated DS1100LZ-45

Overview

DS1100LZ-45 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal tap delays of 9ns, 18ns, 27ns, 36ns, and 45ns. It operates from 3.0V to 3.6V across –40°C to +85°C, reproduces both leading and trailing edges with equal precision, and drives up to 10 74LS loads per tap-used in high-speed timing alignment and signal skew correction in digital logic systems.

For engineers reviewing the DS1100LZ-45 datasheet, DS1100LZ-45 pinout, DS1100LZ-45 application, or DS1100LZ-45 equivalent, this page delivers verified electrical specs, package mapping, tap delay tolerances, temperature-voltage stability behavior, and real-world timing use cases without inference or generic claims.

Technical Context

The DS1100LZ-45 implements an all-silicon delay architecture with five fixed, equally spaced taps referenced to a single input edge. Delay accuracy is specified as ±4ns over –40°C to +85°C for delays ≤40ns (e.g., TAP 1–TAP 4), and ±13% for TAP 5 (45ns), with unidirectional drift across voltage and temperature-ensuring monotonic delay shift across all taps.

It uses CMOS-compatible TTL-level inputs and outputs, supports 1MHz maximum input frequency, and achieves sub-nanosecond edge fidelity via 1.5V threshold timing measurement points. Power-up time is 200μs, and input pulse width must exceed 20% of TAP 5 delay (≥9ns) for stable operation.

FAQ

What is the operating voltage range for DS1100LZ-45?

The DS1100LZ-45 operates from 3.0V to 3.6V. This 3.3V-specific range ensures compatibility with standard LVTTL and LVCMOS logic families. Operation outside this window risks timing inaccuracy or functional failure. The device draws 10mA typical active current at 1MHz under these conditions, and its delay values are characterized and guaranteed across the full voltage span. DS1100LZ-45 does not support 5V operation.

How accurate are the tap delays of DS1100LZ-45 over temperature?

For DS1100LZ-45, tap delays ≤40ns (TAP 1–TAP 4) have a tolerance of ±4ns over –40°C to +85°C. TAP 5 (45ns) has ±13% tolerance, or ±5.9ns. All taps exhibit unidirectional drift-e.g., if TAP 1 slows, all others slow proportionally-enabling predictable skew management. DS1100LZ-45's delay stability is validated per Maxim's test conditions using 1.5V threshold measurements.

Can DS1100LZ-45 drive standard TTL loads directly?

Yes, DS1100LZ-45 can drive up to 10 × 74LS loads per tap. Its output drive capability is specified as 8mA sink and –1mA source at minimum VCC (3.0V), meeting 74LS input current requirements. No external buffer is needed for typical logic interfacing. DS1100LZ-45 maintains TTL/CMOS compatibility with VIH ≥2.0V and VIL ≤0.8V, ensuring robust noise margins in mixed-logic systems.

What package type is used for DS1100LZ-45, and is it RoHS-compliant?

DS1100LZ-45 is packaged in an 8-pin SO (Small Outline, 150-mil width) with RoHS-compliant, lead(Pb)-free construction denoted by the "+" suffix. It supports vapor-phase and IR reflow soldering up to +260°C. The land pattern corresponds to Maxim outline no. 21-0041 and footprint 90-0096. DS1100LZ-45's package is optimized for automated assembly and high-density PCB layouts.

Does DS1100LZ-45 reproduce both rising and falling edges with equal precision?

Yes, DS1100LZ-45 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH and tPHL delays are matched within specification across all taps and operating conditions. This edge symmetry preserves pulse width integrity-critical in applications like strobe generation, clock forwarding, and data eye alignment. DS1100LZ-45 achieves this via matched internal path design and 1.5V-level timing measurement methodology.
