Analog Devices Inc./Maxim Integrated DS1110E-80+

Overview

DS1110E-80+ from Maxim Integrated is a 10-tap silicon delay line in 14-pin TSSOP, delivering precise 80ns total delay (8ns per tap) with ±5% or ±2ns tolerance at 5V/+25°C. It reproduces input logic state at Tap 10 with equal leading- and trailing-edge accuracy and drives up to ten 74LS loads-used in high-speed timing alignment for automated test equipment and communications interfaces.

For engineers reviewing the DS1110E-80+ datasheet, DS1110E-80+ pinout, DS1110E-80+ application, or DS1110E-80+ equivalent, key selection criteria include tap spacing consistency, edge-matched delay tolerance, industrial temperature support (-40°C to +85°C), TTL/CMOS compatibility, and TSSOP package suitability for dense PCB layouts.

Technical Context

The DS1110E-80+ implements an all-silicon, low-power CMOS delay architecture with fixed, equally spaced taps-no external components required. Its delay stability is characterized over voltage (4.75V–5.25V) and temperature (-40°C to +85°C), with unidirectional drift across all taps under varying conditions.

It supports both rising- and falling-edge delay measurement at the 1.5V logic threshold, with input pulse width ≥10ns and period ≥20ns. Active current ranges from 40mA to 150mA depending on frequency and load, and it features no internal termination-requiring external 50Ω source impedance for specified timing accuracy.

FAQ

What is the exact total delay and tap spacing of the DS1110E-80+?

The DS1110E-80+ provides a nominal total delay of 80ns from IN to Tap 10, with precisely equal 8ns spacing between consecutive taps (Tap 1 = 8ns, Tap 2 = 16ns, ..., Tap 10 = 80ns). This fixed, linear progression is factory-trimmed and verified per datasheet Table 1, and applies across the full -40°C to +85°C operating range.

Does the DS1110E-80+ support both rising- and falling-edge delay measurement?

Yes, the DS1110E-80+ is explicitly designed for equal leading- and trailing-edge delay precision. Both tPLH (rising) and tPHL (falling) delays are specified identically in the AC Electrical Characteristics table, measured at the 1.5V logic threshold, and guaranteed within the same ±5% or ±2ns tolerance band at 5V/+25°C.

What is the maximum capacitive load the DS1110E-80+ can drive per tap?

The DS1110E-80+ is rated to drive up to ten 74LS-type loads per tap-equivalent to approximately 10 × 20pF = 200pF total load capacitance. Driving heavier loads may degrade delay accuracy and edge rate; for >200pF, a buffer such as SN74LVC1G125 is recommended to maintain specified timing performance.

Is the DS1110E-80+ pin-compatible with the older DS1010 delay line?

Yes-the DS1110E-80+ is documented as an improved drop-in replacement for the DS1010. It retains identical pin functions and package footprint (14-pin TSSOP), enabling direct substitution without PCB modification. However, DS1110E-80+ delivers tighter delay tolerance (±5% vs. older DS1010's ±10%) and enhanced temperature stability.

What are the recommended PCB layout practices for optimal DS1110E-80+ timing accuracy?

To preserve DS1110E-80+ delay accuracy, use short, matched-length traces for IN and all TAP outputs; place a 0.1µF ceramic decoupling capacitor within 2mm of the VCC pin; connect GND pin directly to solid ground plane with multiple vias; avoid routing high-speed signals adjacent to delay lines; and maintain 50Ω source impedance on the IN signal using series termination if needed.
