Analog Devices Inc./Maxim Integrated DS1100Z-35

Overview

DS1100Z-35 from Maxim Integrated is a 5-tap silicon delay line IC providing fixed, equally spaced delays of 7ns, 14ns, 21ns, 28ns, and 35ns 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. It serves as a precision timing element in digital signal alignment, clock deskewing, and pulse width adjustment circuits.

For engineers reviewing the DS1100Z-35 datasheet, DS1100Z-35 pinout, DS1100Z-35 application, or DS1100Z-35 equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, low-power CMOS operation, SOIC packaging for automated assembly, and guaranteed edge fidelity for high-speed logic synchronization.

Technical Context

The DS1100Z-35 implements an all-silicon delay architecture with five fixed, linearly spaced output taps derived from a monolithic CMOS delay chain. Each tap delivers identical propagation characteristics for rising and falling edges, with delay tolerance specified as ±4ns (for ≤40ns delays) over full industrial temperature range.

It operates exclusively at 5V (4.75V–5.25V), draws 30–50mA active current, and features input leakage <±1μA. The device is fully compatible with TTL and CMOS logic families, supports vapor-phase, IR, and wave soldering, and requires no external components for basic operation.

FAQ

What is the maximum operating frequency supported by DS1100Z-35?

The DS1100Z-35 does not specify a maximum operating frequency but defines valid operation based on input pulse width and period. Per datasheet test conditions, a 1μs period (1MHz) is used for characterization. Higher frequencies increase ICC and may reduce delay accuracy due to layout sensitivity and decoupling limitations. For reliable operation, maintain input pulse width ≥20% of TAP 5 delay (i.e., ≥7ns) and ensure proper 50Ω source impedance and local VCC decoupling. DS1100Z-35 remains functional beyond 1MHz but requires careful board-level validation.

Does DS1100Z-35 support both rising and falling edge delays with equal accuracy?

Yes, DS1100Z-35 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 -40°C to +85°C range, ensuring pulse width integrity across temperature and voltage variations. This behavior is confirmed in AC Electrical Characteristics and Timing Diagram sections of the datasheet, and applies identically to all five taps. DS1100Z-35 thus preserves duty cycle in delay applications where edge symmetry is critical.

Can DS1100Z-35 drive standard 74LS logic directly?

Yes, DS1100Z-35 can drive up to 10 LS-TTL loads per tap, as verified in DC Electrical Characteristics (IOL = 12mA, IOH = -1mA). Its output voltage levels meet TTL thresholds (VOH ≥ 2.4V, VOL ≤ 0.5V at rated load), and its drive strength exceeds the 0.4mA/–1.6mA requirement of a single 74LS input. No buffer stage is needed when interfacing with LS-TTL families. DS1100Z-35 maintains this capability across its full operating temperature and voltage range.

Is DS1100Z-35 pin-compatible with other DS1100 variants like DS1100Z-50 or DS1100U-35?

DS1100Z-35 shares identical pinout and electrical behavior with all DS1100Z-x variants (e.g., DS1100Z-50) in the same SOIC package, differing only in nominal delay values. It is not pin-compatible with DS1100U-35, which uses the 8-pin µMAX package with different physical pin mapping. Board designs using DS1100Z-35 cannot substitute DS1100U-35 without PCB revision. DS1100Z-35 pinout is fixed per SOIC outline S8+4 and validated in Pin Assignment diagrams.

What soldering processes are qualified for DS1100Z-35?

DS1100Z-35 is qualified for vapor-phase, infrared (IR), and wave soldering per manufacturer specifications. Lead(Pb)-free versions (marked with "+") support reflow up to +260°C; leaded versions support +240°C. Maximum lead temperature is +300°C for 10 seconds. These profiles are validated in Absolute Maximum Ratings and Package Information sections. DS1100Z-35's SOIC package complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 1, eliminating bake requirements prior to assembly.
