Analog Devices Inc./Maxim Integrated DS1110E-250+

Overview

DS1110E-250+ from Maxim Integrated is a 10-tap all-silicon delay line delivering precise 250ns total delay (25ns per tap), ±5% or ±2ns accuracy at 5V/+25°C, TTL/CMOS-compatible input/output, and operation across -40°C to +85°C - used for signal alignment in high-speed digital test and medical timing circuits.

For engineers reviewing the DS1110E-250+ datasheet, DS1110E-250+ pinout, DS1110E-250+ application, or DS1110E-250+ equivalent, this page provides verified electrical specs, TSSOP-14 package mapping, leading/trailing-edge delay symmetry, load-driving capability (10 × 74LS), and validated alternatives for timing-critical PCB designs.

Technical Context

The DS1110E-250+ implements a monolithic CMOS delay chain with ten equally spaced taps, where each tap reproduces the input logic state after a fixed cumulative delay - Tap 1 = 25ns, Tap 10 = 250ns. Delay variation is unidirectional across temperature/voltage changes, ensuring monotonic tracking between taps.

It supports both rising-edge (tPLH) and falling-edge (tPHL) delays with identical tolerance (±5% or ±2ns), operates at 5.0V ±5%, and maintains stable performance under 500kHz input frequency with 15pF load per tap - critical for deterministic pulse shaping in ATE and communications synchronization.

FAQ

What is the exact delay tolerance of DS1110E-250+ at 5V and +25°C?

The DS1110E-250+ specifies a delay tolerance of ±5% or ±2ns, whichever is greater, at 5V and +25°C. For its 250ns nominal delay, ±5% equals ±12.5ns, so the actual tolerance is ±12.5ns. This applies identically to both rising (tPLH) and falling (tPHL) edges, ensuring matched timing behavior.

Does DS1110E-250+ support operation outside the commercial temperature range?

Yes, DS1110E-250+ is rated for continuous operation from -40°C to +85°C - an industrial-grade temperature range. All AC and DC specifications, including delay accuracy and output drive strength, are guaranteed across this full range, not just at +25°C.

Can DS1110E-250+ drive modern CMOS loads like 74LVC, or is it limited to 74LS?

DS1110E-250+ is specified to drive up to ten 74LS-type loads per tap, which implies ~0.4mA high-level and ~8mA low-level current. While it can often drive lighter 74LVC loads, the datasheet does not guarantee timing or waveform integrity beyond the 74LS spec - use buffer amplifiers for LVC interfacing if edge fidelity is critical.

Is the DS1110E-250+ pinout compatible with DS1010 series devices?

Yes, DS1110E-250+ is explicitly documented as an improved drop-in replacement for DS1010. Its TSSOP-14 pinout matches DS1010E-250, including identical IN, GND, VCC, and TAP1–TAP10 assignments - allowing direct PCB substitution without layout changes.

How does delay variation behave across temperature for DS1110E-250+?

DS1110E-250+ exhibits monotonic delay variation: all taps shift in the same direction (e.g., all slow down) with temperature or supply voltage changes. This preserves relative tap-to-tap spacing - critical for applications relying on consistent inter-tap intervals, such as multi-phase clock generation.
