Analog Devices Inc./Maxim Integrated DS1100Z-500+T

Overview

DS1100Z-500+T from Maxim Integrated is a 5-tap silicon delay line delivering precisely spaced 100ns, 200ns, 300ns, 400ns, and 500ns delays at each tap under 5V operation, with ±4ns absolute tolerance over -40°C to +85°C, TTL/CMOS-compatible outputs, and ability to drive up to 10 × 74LS loads - used in digital timing alignment, pulse shaping, and clock deskew circuits.

For engineers reviewing the DS1100Z-500+T datasheet, DS1100Z-500+T pinout, DS1100Z-500+T application, or DS1100Z-500+T equivalent, key selection criteria include fixed-tap delay precision, leading/trailing edge matching, industrial temperature stability, SO-8 package compatibility, and 5V CMOS/TTL interface readiness.

Technical Context

The DS1100Z-500+T implements an all-silicon delay architecture with five fixed, equally spaced output taps derived from a single input signal; each tap reproduces both rising and falling edges with matched propagation delay (tPLH = tPHL) and identical temperature/voltage drift behavior across all taps.

It operates exclusively at 5V (4.75V–5.25V), supports input pulse widths ≥500ns for the -500 variant, and maintains delay accuracy within ±4ns (≤40ns taps) or ±13% (＞40ns taps) over full industrial temperature range - with no internal logic, feedback, or programmability.

Key Specifications

Pinout & Package

FAQ

What is the operating voltage range for DS1100Z-500+T?

The DS1100Z-500+T operates from 4.75V to 5.25V DC. It is designed exclusively for 5V logic systems and does not support 3.3V or dual-supply operation. Supply decoupling with a 0.1μF ceramic capacitor placed near the VCC pin is required to maintain delay accuracy and noise immunity. Operation outside this range may cause timing errors or damage the device.

Does DS1100Z-500+T support both rising and falling edge delays?

Yes, the DS1100Z-500+T reproduces both leading and trailing edges with matched propagation delay (tPLH ≈ tPHL) across all five taps. This edge-matching ensures preserved duty cycle and symmetrical timing behavior - critical for clock distribution, pulse shaping, and synchronous sampling applications where waveform integrity matters.

What is the maximum load each tap of DS1100Z-500+T can drive?

Each tap of the DS1100Z-500+T can drive up to 10 × 74LS logic inputs, corresponding to approximately 0.8mA low-level sink current and -1mA high-level source current. Exceeding this load degrades delay accuracy and edge fidelity. For heavier loads, buffer stages such as 74ACT or 74LVC series are recommended before connecting downstream logic.

Is DS1100Z-500+T pin-compatible with earlier DS1000 series devices?

No, the DS1100Z-500+T is not pin-compatible with DS1000 series devices. While both use 8-pin SO packages, the pin assignments differ: DS1100Z-500+T places VCC on pin 1 and GND on pin 8, whereas DS1000 variants use different pinouts. PCB redesign is required when upgrading from DS1000 to DS1100Z-500+T.

What delay tolerances apply to DS1100Z-500+T over temperature?

For DS1100Z-500+T, delay tolerance is ±4ns over the full -40°C to +85°C industrial temperature range. This applies to absolute delay values (e.g., TAP5 = 500ns ±4ns), not percentage deviation. The specification is guaranteed per Maxim's datasheet Rev 3/11 and reflects matched drift behavior across all taps under varying temperature and supply conditions.
