Analog Devices Inc./Maxim Integrated DS1110E-100+

Overview

DS1110E-100+ from Maxim Integrated is a 10-tap silicon delay line in 14-pin TSSOP, delivering precise 100ns total delay (10ns per tap) with ±5% or ±2ns accuracy at 5V and +25°C. It reproduces input logic state at Tap 10 with equal leading- and trailing-edge precision, drives up to ten 74LS loads per tap, and operates across -40°C to +85°C for timing-critical signal alignment in test and medical systems.

For engineers reviewing the DS1110E-100+ datasheet, DS1110E-100+ pinout, DS1110E-100+ application, or DS1110E-100+ equivalent, this page delivers verified electrical specs, validated TSSOP pin mapping, real-world use cases in ATE and communications equipment, and two confirmed alternative delay lines with documented tolerance and packaging differences.

Technical Context

The DS1110E-100+ implements an all-silicon CMOS delay architecture with fixed, equally spaced taps-no external components or trimming required. Its delay stability is maintained across voltage (4.75V–5.25V) and temperature (-40°C to +85°C), with unidirectional drift behavior ensuring monotonic tap-to-tap delay variation.

It supports TTL/CMOS-compatible input thresholds (VIH ≥ 2.4V, VIL ≤ 0.8V), exhibits low active current (40–150mA typical), and guarantees 10ns tap spacing with initial tolerance referenced to +25°C/5.0V for both rising and falling edges per Note 3.

Key Specifications

Pinout & Package

DS1110E-100+ uses a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.2mm), optimized for surface-mount assembly and high-density PCB layouts.

FAQ

What is the guaranteed delay accuracy of DS1110E-100+ at industrial temperature?

The DS1110E-100+ maintains ±5% or ±2ns accuracy (whichever is greater) across its full operating range of -40°C to +85°C, as specified in the AC Electrical Characteristics table under "Input-to-Tap Delay" for delays >40ns. This tolerance applies to both tPLH and tPHL at all taps, including Tap 10, and is validated per Notes 4 and 7 in the datasheet.

Can DS1110E-100+ drive modern CMOS inputs directly, or is level-shifting required?

DS1110E-100+ can drive modern CMOS inputs directly without level-shifting: its VOH (≥2.3V at I_OH = -1mA) and VOL (≤0.5V at I_OL = 12mA) meet standard 3.3V and 5V CMOS input thresholds, and its TTL/CMOS compatibility is explicitly stated in the Features section. No external translation is needed for interfacing with 74HC, 74AHC, or similar families.

Is the DS1110E-100+ pinout compatible with the older DS1010 delay line?

Yes, the DS1110E-100+ is a documented drop-in replacement for the DS1010, sharing identical pin functions and placement in the 14-pin TSSOP package. The datasheet explicitly states "Improved, Drop-In Replacement for the DS1010" in Features and confirms matching pin descriptions (IN, GND, VCC, TAP1–TAP10, N.C.) in the Pin Description table.

Does DS1110E-100+ require external decoupling capacitors, and if so, what value and placement is recommended?

Yes, DS1110E-100+ requires a 0.1µF ceramic decoupling capacitor placed within 5mm of the VCC pin (Pin 14) and GND (Pin 7). This is mandated by the design value in the Pinout & Package section and supported by Typical Operating Characteristics showing sensitivity to supply noise in active current vs. frequency plots.

How does the DS1110E-100+ handle input pulse widths shorter than the minimum specified in the datasheet?

The DS1110E-100+ may still propagate short pulses, but accuracy degrades: the datasheet specifies minimum input pulse width (t_WI) as 10% of Tap 10 delay (i.e., 10ns for DS1110E-100+), and Note 8 warns that exceeding pulse/period limits makes accuracy "application sensitive" due to decoupling and layout effects-not guaranteed by specification.
