Analog Devices Inc./Maxim Integrated DS1100LZ-75+T

Overview

DS1100LZ-75+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 15ns, 30ns, 45ns, 60ns, and 75ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance (–40°C to +85°C), and drives up to 10 LS-TTL loads per tap. Used in high-speed timing alignment, clock deskew, and pulse-width adjustment circuits.

For engineers reviewing the DS1100LZ-75+T datasheet, DS1100LZ-75+T pinout, DS1100LZ-75+T application, or DS1100LZ-75+T equivalent, key selection criteria include tap delay precision across temperature, edge fidelity for dual-edge timing, SO-8 package compatibility, and TTL/CMOS input/output logic levels.

Technical Context

The DS1100LZ-75+T implements an all-silicon delay architecture with five fixed, equally spaced delay taps derived from a monolithic CMOS delay chain. Each tap delivers identical propagation characteristics for rising and falling edges, enabling precise pulse shaping without duty-cycle distortion.

Delay values are calibrated at +25°C and VCC = 3.3V, with specified tolerances tightened by +2ns on TAP1–TAP3 (vs. base DS1100L) per Note 10 - a factory-tested enhancement for critical early-tap accuracy. The device requires no external components and functions with standard 50Ω source impedance and ≤3ns input rise/fall times.

Key Specifications

Pinout & Package

FAQ

What is the operating voltage range for DS1100LZ-75+T?

The DS1100LZ-75+T operates from 3.0V to 3.6V, making it compatible with standard 3.3V logic systems. It is characterized across this full range at temperatures from –40°C to +85°C. Supply voltage directly affects delay stability: variations within this window cause unidirectional delay shifts (e.g., lower VCC increases delay), but all taps track consistently. The DS1100LZ-75+T does not support 5V operation.

How accurate are the tap delays for DS1100LZ-75+T over temperature?

For DS1100LZ-75+T, TAP1–TAP3 delays have ±4ns tolerance over –40°C to +85°C (per Note 10), while TAP4 and TAP5 exhibit ±13% tolerance. This enhanced early-tap accuracy results from factory screening and is specific to the "-75" variant. All taps maintain equal leading/trailing edge precision, ensuring consistent pulse width reproduction across temperature.

Can DS1100LZ-75+T drive standard TTL loads?

Yes, DS1100LZ-75+T can drive up to 10 LS-TTL loads per tap, with IOL = 8mA and IOH = –1mA specified at VCC = 3.0V. Its output voltage levels (VOH ≥ 2.3V, VOL ≤ 0.5V) meet TTL input thresholds, and its 5pF input capacitance minimizes loading on upstream drivers. The DS1100LZ-75+T is explicitly rated for TTL-/CMOS-compatibility in its datasheet.

What is the significance of the "+T" suffix in DS1100LZ-75+T?

The "+T" suffix in DS1100LZ-75+T indicates tape-and-reel packaging in a RoHS-compliant, lead(Pb)-free SO-8 package. The "+" denotes compliance with EU RoHS Directive 2011/65/EU, and "T" specifies carrier tape format - standard for automated SMT placement. This matches the ordering code DS1100LZ-xxx+T defined in Maxim's Ordering Information table.

Does DS1100LZ-75+T require external passive components for operation?

No, DS1100LZ-75+T requires no external resistors, capacitors, or inductors to function. A 0.1μF ceramic bypass capacitor between VCC and GND is strongly recommended near the package for noise suppression, but it is not part of the core timing circuit. The DS1100LZ-75+T integrates all delay elements monolithically in silicon and operates with only power, ground, and input signal connections.
