Analog Devices Inc./Maxim Integrated DS1100Z-50/T&R+MOT

Overview

DS1100Z-50/T&R+MOT from Maxim Integrated is a 5-tap silicon delay line delivering precise, fixed delays of 10ns, 20ns, 30ns, 40ns, and 50ns per tap, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads-used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100Z-50/T&R+MOT datasheet, DS1100Z-50/T&R+MOT pinout, DS1100Z-50/T&R+MOT application, or DS1100Z-50/T&R+MOT equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, SO-8 package footprint, and industrial-grade operating range.

Technical Context

The DS1100Z-50/T&R+MOT implements an all-silicon delay architecture with five equally spaced taps, each reproducing both leading and trailing edges with equal precision at 1.5V switching threshold. Delay values are factory-trimmed and specified with ±4ns absolute tolerance over full industrial temperature range (-40°C to +85°C) at 5V supply.

It features low-power CMOS design, TTL/CMOS input compatibility (VIH = 2.2V min, VIL = 0.8V max), and output drive capability matching 74LS logic families. Input-to-tap propagation delay (tPLH/tPHL) is measured between 1.5V points on input and output waveforms under controlled test conditions.

FAQ

What is the nominal delay value for each tap of the DS1100Z-50/T&R+MOT?

The DS1100Z-50/T&R+MOT provides five equally spaced delays: TAP 1 = 10ns, TAP 2 = 20ns, TAP 3 = 30ns, TAP 4 = 40ns, and TAP 5 = 50ns. These values are factory-trimmed and specified at +25°C and 5V, with monotonic behavior across temperature and supply voltage. Each tap reproduces both rising and falling edges with matched precision, and the DS1100Z-50/T&R+MOT maintains this spacing without interpolation or configuration.

Is the DS1100Z-50/T&R+MOT compatible with 3.3V logic inputs?

The DS1100Z-50/T&R+MOT is designed for 5V operation and specifies TTL/CMOS-compatible inputs with VIH ≥ 2.2V and VIL ≤ 0.8V. While a 3.3V logic high may exceed VIH minimum, it falls below VCC and risks marginal noise margin or undefined behavior under voltage droop. For robust 3.3V interface, level translation is recommended. The DS1100Z-50/T&R+MOT does not support 3.3V supply or guaranteed 3.3V input operation per its datasheet.

Does the DS1100Z-50/T&R+MOT require external decoupling capacitors?

Yes-the DS1100Z-50/T&R+MOT requires a 0.1µF ceramic capacitor placed as close as possible to the VCC (pin 8) and GND (pin 7) pins. This decoupling minimizes supply-induced jitter and ensures stable delay accuracy, especially during fast edge transitions. The DS1100Z-50/T&R+MOT datasheet specifies this as mandatory for meeting ±4ns tolerance across temperature and load conditions.

Can the DS1100Z-50/T&R+MOT drive modern CMOS loads like 74LVC or 74AUC?

The DS1100Z-50/T&R+MOT is characterized to drive up to 10× 74LS loads (12mA sink, -1mA source), which exceeds typical 74LVC or 74AUC input current requirements (<10µA). However, its output voltage swing is referenced to VCC (5V), so interfacing with 3.3V CMOS families requires level shifting to avoid overvoltage damage. The DS1100Z-50/T&R+MOT itself operates correctly under load but must be used within voltage domain boundaries.

What does the "+MOT" suffix indicate in DS1100Z-50/T&R+MOT?

The "+MOT" suffix in DS1100Z-50/T&R+MOT indicates Maxim's internal manufacturing lot code and tape-and-reel packaging designation per their ordering convention; "+" denotes RoHS-compliant (lead-free) finish, "T&R" confirms tape-and-reel packaging, and "MOT" identifies the specific production facility and material traceability batch. It does not alter electrical specs-the DS1100Z-50/T&R+MOT performs identically to DS1100Z-50+T&R per datasheet specifications.
