Analog Devices Inc./Maxim Integrated DS1100Z-500

Overview

DS1100Z-500 from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced 100ns, 200ns, 300ns, 400ns, and 500ns delays at each tap under 5V operation. It reproduces both leading and trailing edges with ±4ns tolerance over -40°C to +85°C, drives up to 10 LS-TTL loads per tap, and is housed in an 8-pin SOIC (150 mil) package for PCB space efficiency in timing-critical digital systems.

For engineers reviewing the DS1100Z-500 datasheet, DS1100Z-500 pinout, DS1100Z-500 application, or DS1100Z-500 equivalent, key selection criteria include fixed-tap delay accuracy across temperature/voltage, edge fidelity for pulse shaping, TTL/CMOS compatibility, and industrial-grade reliability in surface-mount timing circuits.

Technical Context

The DS1100Z-500 implements a monolithic all-silicon delay architecture-no hybrid or ceramic components-with five equally spaced taps derived from a single propagation path. Delay values are factory-trimmed and specified with ±4ns absolute tolerance (for delays >40ns: ±13% over -40°C to +85°C), ensuring deterministic timing without external calibration.

Each tap operates with matched tPLH/tPHL characteristics, maintaining consistent edge alignment across all outputs. Input-to-output delay is measured at the 1.5V logic threshold, and the device supports 1MHz input frequency with active current draw of 30–50mA at VCC = 5V.

FAQ

What is the absolute delay tolerance of DS1100Z-500 over its full operating temperature range?

The DS1100Z-500 has an absolute delay tolerance of ±4ns for all taps over -40°C to +85°C, as specified in the AC Electrical Characteristics table. This applies to the nominal 100ns–500ns delays and reflects worst-case deviation from the 25°C/5V value. The tolerance is tighter than percentage-based specs for shorter delays, ensuring predictable inter-tap skew in timing-critical paths.

Can DS1100Z-500 drive standard TTL loads directly without buffer amplification?

Yes, DS1100Z-500 can drive up to 10 × 74LS loads per tap, as confirmed in the General Description and DC Electrical Characteristics (IOL = 12mA min). Its output drive strength meets TTL fan-out requirements at VCC = 5V, eliminating the need for external buffers in most logic interfacing scenarios.

Is DS1100Z-500 pin-compatible with other DS1100 variants such as DS1100Z-200 or DS1100U-500?

DS1100Z-500 shares identical pinout and electrical behavior with all DS1100Z-x variants (same SOIC-8 package and terminal mapping), but is not pin-compatible with DS1100U-500, which uses the 8-pin µMAX package with different physical pin locations. Board redesign is required when substituting between Z and U suffixes.

Does DS1100Z-500 require external decoupling capacitors, and if so, what value is recommended?

Yes, DS1100Z-500 requires a 0.1µF ceramic decoupling capacitor placed as close as possible to the VCC (pin 8) and GND (pin 7) pins. This is explicitly stated in the Test Conditions section and is critical to maintain delay stability and suppress supply-induced jitter, especially at higher input frequencies.

How does DS1100Z-500 handle input pulse widths near its maximum specification?

DS1100Z-500 specifies a minimum input pulse width of 500ns for the -500 version (per Test Conditions). Pulses narrower than this may result in degraded delay accuracy due to internal propagation effects and are not guaranteed per datasheet. For reliable operation, maintain input pulse width ≥500ns and rise/fall times ≤3ns.
