Analog Devices Inc./Maxim Integrated DS1110E-400+

Overview

DS1110E-400+ from Maxim Integrated is a 10-tap silicon delay line in 14-pin TSSOP, delivering precisely spaced 40ns increments (TAP1–TAP10) for total 400ns fixed delay, ±5% or ±2ns accuracy at 5V/+25°C, TTL/CMOS-compatible, and designed for leading- and trailing-edge timing control in high-speed digital synchronization circuits.

For engineers reviewing the DS1110E-400+ datasheet, DS1110E-400+ pinout, DS1110E-400+ application, or DS1110E-400+ equivalent, key selection criteria include tap spacing consistency, edge-matched delay tolerance, industrial temperature range support (-40°C to +85°C), load drive capability (10 × 74LS), and TSSOP package compatibility with automated assembly.

Technical Context

The DS1110E-400+ implements an all-silicon, low-power CMOS delay architecture with unidirectional temperature/voltage drift-ensuring monotonic delay variation across all taps. Its fixed 400ns total delay is subdivided into ten equally spaced 40ns intervals, each validated for both tPLH and tPHL with identical ±5% or ±2ns tolerance.

Designed as a drop-in replacement for DS1010, it maintains identical functional behavior while improving delay stability and edge precision. Input-to-tap propagation is measured at 1.5V thresholds, supporting reliable operation with 50Ω source impedance, ≤3ns input rise/fall time, and pulse widths ≥10% of tap10 delay.

FAQ

What is the exact delay value per tap for DS1110E-400+?

The DS1110E-400+ provides ten equally spaced taps with 40ns increments: TAP1 = 40ns, TAP2 = 80ns, ..., TAP10 = 400ns. This 40ns step is fixed and confirmed in Table 1 of the official datasheet. Each tap reproduces the input logic state after its respective delay, with identical ±5% or ±2ns tolerance applied to every tap under 5V/+25°C conditions. The DS1110E-400+ does not support programmable or variable tap spacing.

Does DS1110E-400+ support both rising and falling edge delays with equal accuracy?

Yes, the DS1110E-400+ is explicitly designed for leading- and trailing-edge delay precision. Its datasheet specifies identical tPLH (rising edge) and tPHL (falling edge) tolerances-±5% or ±2ns-measured at the 1.5V threshold. This edge-matched behavior is verified across the full -40°C to +85°C range and ensures zero added skew between complementary signal paths, making DS1110E-400+ suitable for DDR clock forwarding and differential timing applications.

Can DS1110E-400+ drive standard TTL loads directly?

Yes, each tap of the DS1110E-400+ can drive up to ten 74LS-type loads without external buffering. Electrical specifications confirm IOL = 12mA (min) and IOH = -1.0mA (min) at VCC = 4.75V, meeting 74LS input current requirements (IIL = -0.4mA, IIH = 20µA). This capability is validated across the full industrial temperature range and eliminates fanout logic in most digital timing circuits using DS1110E-400+.

What is the recommended power supply decoupling for DS1110E-400+?

A 0.1µF ceramic capacitor must be placed within 5mm of the DS1110E-400+ VCC pin (Pin 14) and GND (Pin 13), as specified in the "Test Conditions" section and layout guidance. This decoupling is critical to maintain ±2ns delay accuracy-insufficient bypassing increases supply-induced delay variation, especially under fast-switching load conditions. No additional bulk capacitance is required unless shared with other high-current devices on the same rail.

Is DS1110E-400+ pin-compatible with DS1010 series devices?

Yes, the DS1110E-400+ is documented as an improved drop-in replacement for DS1010. Pin functions (IN, GND, VCC, TAP1–TAP10, N.C.) match identically between DS1110E-400+ (14-pin TSSOP) and DS1010E variants. However, DS1110E-400+ improves delay accuracy (±5% vs. older DS1010 spec) and adds edge-matched tPLH/tPHL performance-so existing DS1010 layouts accept DS1110E-400+ without modification, but timing margins improve.
