Analog Devices Inc./Maxim Integrated DS1110E-100

Overview

DS1110E-100 from Maxim Integrated (formerly Dallas Semiconductor) is a 10-tap silicon delay line IC providing fixed, equally spaced delays of 10ns per tap up to 100ns total, with ±5% or ±2ns accuracy at 5V and +25°C, TTL/CMOS-compatible inputs/outputs, and operation across -40°C to +85°C. It reproduces input logic states at Tap 10 after precisely 100ns, supporting leading- and trailing-edge timing in high-speed digital synchronization circuits.

For engineers reviewing the DS1110E-100 datasheet, DS1110E-100 pinout, DS1110E-100 application, or DS1110E-100 equivalent, key selection factors include its 14-pin TSSOP package, 10ns/tap resolution, ±2ns absolute delay tolerance at 100ns, 5V CMOS/TTL compatibility, and guaranteed drive capability for ten 74LS loads per tap - critical for test equipment and medical timing subsystems.

Technical Context

The DS1110E-100 implements an all-silicon, monolithic delay line architecture with ten discrete output taps derived from a single propagation path, ensuring unidirectional temperature/voltage drift across all taps. Its delay is specified at the 1.5V logic threshold for both rising (t_PLH) and falling (t_PHL) edges, with identical tolerance bands for both edge types.

It operates exclusively at V_CC = 5.0V ±5% and supports input pulse widths ≥10ns (at 10% of Tap 10 delay), with active current ranging 40–150mA depending on frequency and load. Power-up time is 200ms, and it requires no external configuration or clock source - functioning as a passive, deterministic signal delay element.

Key Specifications

FAQ

What is the exact delay tolerance of DS1110E-100 at room temperature and 5V?

The DS1110E-100 specifies a delay tolerance of ±5% or ±2ns, whichever is greater, at +25°C and V_CC = 5.0V. For its 100ns nominal delay, this yields a guaranteed range of 98ns to 102ns - confirmed by production testing per Maxim's datasheet Table 1 and AC Electrical Characteristics section.

Does DS1110E-100 support both rising and falling edge delays with equal accuracy?

Yes, DS1110E-100 is explicitly designed for leading- and trailing-edge delay precision. Its t_PLH (rising) and t_PHL (falling) delays are matched within the same ±2ns tolerance band at 100ns, as documented in the "Detailed Description" and "AC Electrical Characteristics" sections of the datasheet.

Can DS1110E-100 drive standard TTL loads directly?

Yes, DS1110E-100 can drive up to ten 74LS-type loads per tap, with I_OL = 12mA and I_OH = -1mA specified at V_CC = 4.75V. This meets the DC loading requirements of legacy TTL and modern 5V CMOS logic without external buffers.

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

Yes, DS1110E-100 is an improved drop-in replacement for DS1010. Both share identical 14-pin TSSOP pinout, electrical interface, and functional behavior - enabling direct substitution without PCB or firmware changes, as stated in the "Features" and "Detailed Description" sections.

What is the maximum operating frequency supported by DS1110E-100?

DS1110E-100 does not have a defined maximum operating frequency, but its minimum input pulse width is specified as 10ns (at 10% of Tap 10 delay). With a 100ns delay, this corresponds to a practical upper limit of ~50MHz for reliable operation - consistent with typical use in burst-mode ATE and medical timing applications.
