Analog Devices Inc./Maxim Integrated DS1110S-50

Overview

DS1110S-50 from Maxim Integrated is a 10-tap silicon delay line IC delivering fixed 50ns total delay with ±5% or ±2ns accuracy (whichever greater) at 5V and +25°C, featuring equally spaced taps (5ns/tap), TTL/CMOS compatibility, and operation across -40°C to +85°C. It reproduces input logic states at Tap 10 with equal leading- and trailing-edge precision for timing alignment in high-speed digital systems.

For engineers reviewing the DS1110S-50 datasheet, DS1110S-50 pinout, DS1110S-50 application, or DS1110S-50 equivalent, this page provides verified electrical specs, tap-specific delay behavior, SO package layout, industrial temperature validation, and drop-in alternatives for signal synchronization in test equipment and communications hardware.

Technical Context

The DS1110S-50 implements an all-silicon, low-power CMOS delay architecture with ten discrete output taps, each providing deterministic propagation delay relative to the IN signal. Delay values scale linearly per tap (Tap 1 = 5ns, Tap 2 = 10ns, ..., Tap 10 = 50ns), with unidirectional variation across voltage (4.75V–5.25V) and temperature (-40°C to +85°C).

Each tap drives up to ten 74LS loads while maintaining ±5% or ±2ns tolerance on rising/falling edges. Input pulse width must be ≥10ns, and active current ranges from 40mA to 150mA depending on frequency and load - validated under commercial and industrial temperature conditions.

FAQ

What is the exact delay value at Tap 10 for DS1110S-50?

The DS1110S-50 delivers a nominal 50ns delay at Tap 10, with tolerance of ±5% or ±2ns (whichever is greater) measured at 5V and +25°C. This value remains consistent across all ten taps in 5ns increments - Tap 1 = 5ns, Tap 2 = 10ns, up to Tap 10 = 50ns - and is validated over the full -40°C to +85°C operating range.

Does DS1110S-50 support both rising and falling edge delays with equal accuracy?

Yes, the DS1110S-50 is explicitly designed for equal leading- and trailing-edge delay precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) exhibit identical ±5% or ±2ns tolerance at Tap 10, ensuring duty-cycle integrity in clock forwarding and pulse-width-sensitive applications.

Can DS1110S-50 drive standard TTL loads directly?

Yes, each tap of the DS1110S-50 can drive up to ten 74LS-type loads, with guaranteed 12mA sink current and -1mA source current at VCC = 4.75V. This meets or exceeds standard TTL fan-out requirements without external buffering, simplifying interface design in legacy logic systems.

Is DS1110S-50 pin-compatible with the older DS1010 delay line?

Yes, the DS1110S-50 is documented as an improved, drop-in replacement for the DS1010 in the same 16-pin SO package. Pin functions, spacing, and electrical behavior match exactly - allowing direct substitution without PCB modification or firmware changes.

What is the maximum input frequency supported by DS1110S-50?

The DS1110S-50 supports input periods as short as 2×tWI (pulse width), with minimum tWI = 10ns. Thus, the practical maximum input frequency is 50MHz (20ns period). Active current increases with frequency - ranging from 40mA at low frequencies to 150mA at 50MHz - and remains within specification across the full -40°C to +85°C range.
