Analog Devices Inc./Maxim Integrated DS1135Z-6+

Overview

DS1135Z-6+ from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V with identical 6 ns propagation delays (tPLH/tPHL) on all three outputs, ±1.0 ns initial tolerance, and precise leading/trailing edge matching for signal integrity in timing-critical logic paths. It replaces DS1013/DS1035 in clock distribution and pulse shaping applications.

For engineers reviewing the DS1135Z-6+ datasheet, DS1135Z-6+ pinout, DS1135Z-6+ application, or DS1135Z-6+ equivalent, this page delivers verified timing specs, SOIC-8 package details, industrial temperature support (–40°C to +85°C), and direct alternatives for logic delay line selection in FPGA interface, test equipment, and digital synchronization systems.

Technical Context

The DS1135Z-6+ implements three independent buffered delay paths within a single silicon die, each delivering matched 6 ns fixed delay with sub-nanosecond edge accuracy. Its architecture preserves input signal symmetry by maintaining equal tPLH and tPHL values across all channels under 4.75–5.25 V supply and full industrial temperature range.

Each output drives up to 10 LS-TTL loads with 2.0–2.5 ns rise/fall times and operates with 100% tap delay input pulse width compliance. Power-up stabilization completes within 100 ms, and input capacitance is specified at 10 pF.

FAQ

What is the guaranteed delay accuracy of DS1135Z-6+ over its full operating temperature range?

The DS1135Z-6+ guarantees ±1.5 ns delay variation (tPLH/tPHL) over –40°C to +85°C and 4.75–5.25 V supply, measured against the nominal 6 ns value. This specification is validated per Table 1 and confirmed in the AC Electrical Characteristics section of the official datasheet. DS1135Z-6+ achieves this stability through all-silicon design and on-die trimming, eliminating quartz-based drift mechanisms. No external calibration is required to meet this spec.

Can DS1135Z-6+ be used with 3.3 V logic systems?

No - DS1135Z-6+ is specified exclusively for +5 V operation (4.75–5.25 V). For 3 V systems, Maxim recommends the DS1135L family, which shares the same 3-channel buffered delay architecture but is optimized for 2.7–3.6 V supply. Interfacing DS1135Z-6+ directly with 3.3 V logic risks violating VIH/VIL thresholds and may cause unreliable switching or increased ICC. DS1135Z-6+ must be powered from a dedicated 5 V rail.

Does DS1135Z-6+ support differential or complementary outputs?

No - DS1135Z-6+ provides three single-ended CMOS/TTL-compatible outputs (OUT1–OUT3). It does not generate differential pairs or complementary signals. Each output replicates its corresponding input with fixed 6 ns delay and standard logic voltage levels (VOH ≥ 4.0 V, VOL ≤ 0.5 V at specified loads). For differential delay applications, consider purpose-built devices such as the MC100EP195DG, but note DS1135Z-6+ is not pin- or functionally compatible with such parts.

How many LS-TTL loads can each output of DS1135Z-6+ drive reliably?

Each output of DS1135Z-6+ is rated to drive up to 10 LS-TTL loads, as stated in the Description section and confirmed by the DC Electrical Characteristics table (IOL = 12 mA min at VOL = 0.5 V). This drive strength ensures clean signal integrity across typical backplane or ribbon-cable fanouts without external buffering. Exceeding 10 LS loads may degrade rise/fall times and delay accuracy. DS1135Z-6+'s output stage is designed for this exact loading condition.

Is DS1135Z-6+ pin-compatible with the older DS1013 or DS1035?

Yes - DS1135Z-6+ is explicitly recommended as a replacement for DS1013 and DS1035, and shares the same 8-pin SOIC (150-mil) footprint and pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND). The DS1135Z-6+ improves upon those predecessors with higher speed, tighter delay tolerance (±1.0 ns vs. ±2.5 ns), and enhanced temperature stability. No PCB layout changes are required when upgrading from DS1013/DS1035 to DS1135Z-6+.
