Analog Devices Inc./Maxim Integrated DS1110S-500

Overview

DS1110S-500 from Maxim Integrated is a 10-tap all-silicon delay line in 16-pin SO package, delivering precisely spaced 50ns per tap with total 500ns fixed delay, ±5% or ±2ns accuracy at 5V/+25°C, and TTL/CMOS compatibility for timing alignment in high-speed digital systems.

For engineers reviewing the DS1110S-500 datasheet, DS1110S-500 pinout, DS1110S-500 application, or DS1110S-500 equivalent, this page provides verified tap delay values, temperature/voltage stability data, load-driving capability (10 × 74LS), and validated drop-in replacement context versus DS1010 and DS1110E-500.

Technical Context

The DS1110S-500 implements a monolithic CMOS silicon delay line architecture with ten equally spaced taps-each incrementing by exactly 50ns-enabling precise edge-aligned signal replication across both rising and falling edges. Delay tolerance is specified as ±5% or ±2ns (whichever greater) at 5V and +25°C, with unidirectional drift across temperature and supply voltage.

It operates over -40°C to +85°C, supports 500kHz maximum input frequency, draws ≤150mA active current at VCC = 5.25V, and drives up to ten 74LS loads per tap while maintaining 1.5V switching threshold timing reference points for tPLH/tPHL measurement.

FAQ

What is the exact delay value at Tap 10 for DS1110S-500?

The DS1110S-500 delivers a nominal 500ns fixed delay at Tap 10, with tolerance of ±5% or ±2ns (whichever is greater) under conditions of 5.0V supply and +25°C ambient temperature. This value is confirmed in Table 1 and the Selector Guide of the official Maxim datasheet, and applies identically to all ten taps with 50ns uniform spacing.

Is DS1110S-500 pin-compatible with DS1010?

Yes, DS1110S-500 is an improved drop-in replacement for DS1010, retaining identical pinout, electrical interface, and functional behavior. The datasheet explicitly states "Improved, Drop-In Replacement for the DS1010", and pin configurations confirm matching VCC, GND, IN, and Tap assignments in the 16-pin SO package.

Can DS1110S-500 operate outside the 5V supply range?

No - DS1110S-500 is specified only for 4.75V to 5.25V operation. Absolute maximum ratings limit voltage on any pin to -0.5V to +6.0V, but functional performance (delay accuracy, output drive, timing margins) is guaranteed solely within the 5V ±5% range per DC and AC Electrical Characteristics tables.

Does DS1110S-500 support both rising and falling edge delays with equal accuracy?

Yes, DS1110S-500 is explicitly designed to produce both leading- and trailing-edge delays with equal precision. The datasheet states "designed to produce both leading- and trailing-edge delays with equal precision", and AC specifications list matched tPLH and tPHL tolerances across all temperature and voltage conditions.

What is the maximum input frequency supported by DS1110S-500?

DS1110S-500 supports input frequencies up to 500kHz, as shown in the Typical Operating Characteristics plots (toc01 and toc02). Input period must be ≥2× pulse width or ≥20ns (whichever greater), and pulse width must be ≥10ns for Tap 10 - limiting practical maximum frequency to 500kHz under standard operating conditions.
