Analog Devices Inc./Maxim Integrated DS1135Z-10/T&R

Overview

DS1135Z-10/T&R from Maxim Integrated is a high-speed, all-silicon 3-in-1 delay line operating at +5V with three independent buffered outputs, each delivering precisely matched 10 ns propagation delay (tPLH/tPHL), ±1.0 ns initial tolerance, and ±1.5 ns variation over -40°C to +85°C. It preserves input signal symmetry via leading/trailing edge accuracy and drives up to 10 LS TTL loads-used in clock skew management, pulse width adjustment, and digital timing alignment in industrial control systems.

For engineers reviewing the DS1135Z-10/T&R datasheet, DS1135Z-10/T&R pinout, DS1135Z-10/T&R application, or DS1135Z-10/T&R equivalent, key selection criteria include guaranteed 10 ns delay matching across all three outputs, SOIC-8 (150-mil) package compatibility, 5V-only operation, industrial temperature support, and direct replacement suitability for legacy DS1013/DS1035 designs.

Technical Context

The DS1135Z-10/T&R implements three independent, fully buffered delay paths within a single silicon die-each path delivers identical 10 ns nominal tPLH and tPHL with matched edge-to-edge performance. Its architecture eliminates analog drift mechanisms found in RC-based delay lines, ensuring stable delay over voltage (4.75V–5.25V) and temperature (-40°C to +85°C).

All outputs are TTL-compatible with 12 mA low-level drive capability and -1.0 mA high-level sink current, supporting direct interfacing with 74F-series logic. Input-to-output timing is measured at the 1.5 V threshold, with rise/fall times ≤2.5 ns and power-up stabilization within 100 ms.

FAQ

What is the exact delay value and tolerance specification for DS1135Z-10/T&R?

The DS1135Z-10/T&R delivers a nominal 10 ns propagation delay (tPLH and tPHL) on each of its three outputs. Initial tolerance is ±1.0 ns at +25°C and 5.0 V. Over the full industrial temperature range (-40°C to +85°C) and supply voltage (4.75V–5.25V), delay variation is limited to ±1.5 ns. These values are guaranteed per Maxim's datasheet Table 1 and apply identically to IN1→OUT1, IN2→OUT2, and IN3→OUT3.

Is DS1135Z-10/T&R compatible with 3V logic systems?

No, DS1135Z-10/T&R operates exclusively at +5V ±5% and is not compatible with 3V logic families. Its input thresholds (VIH ≥2.2 V, VIL ≤0.8 V) and output drive levels are specified only for 5V operation. For 3V systems, Maxim specifies the DS1135L family-select DS1135L-10/T&R instead. Using DS1135Z-10/T&R with 3V supplies risks undefined behavior, insufficient noise margin, and potential damage due to out-of-spec bias conditions.

Does DS1135Z-10/T&R require external passive components for basic operation?

No, DS1135Z-10/T&R requires no external resistors, capacitors, or crystals for core delay functionality. Only standard power supply decoupling is needed: a 0.1 µF ceramic capacitor placed as close as possible between VCC and GND pins. No pull-up/down resistors, termination networks, or timing-setting components are required-the 10 ns delay is factory-trimmed and fully integrated.

Can DS1135Z-10/T&R replace DS1013 or DS1035 in existing designs?

Yes, DS1135Z-10/T&R is explicitly recommended by Maxim as a drop-in replacement for DS1013 and DS1035. It shares the same 8-pin SOIC-150-mil footprint, pinout, and 5V supply requirement. Key improvements include faster speed, tighter delay tolerance (±1.0 ns vs. ±5 ns typical), and enhanced temperature stability. No PCB or schematic changes are needed-only verify that the 10 ns delay meets the target timing window.

What is the maximum load DS1135Z-10/T&R can drive per output?

Each output of DS1135Z-10/T&R is rated to drive up to 10 LS-TTL loads, defined as the input characteristics of a standard 74F04 gate. This corresponds to a worst-case low-level output current of 12 mA and high-level output current of -1.0 mA. Driving heavier capacitive or current loads may degrade delay accuracy, increase rise/fall times, or cause output voltage droop-verify load conditions against the AC Electrical Characteristics table in the DS1135Z-10/T&R datasheet.
