Analog Devices Inc./Maxim Integrated MXD1005SA075

Overview

MXD1005SA075 from Maxim Integrated is a 5-tap silicon delay line with fixed 75ns nominal delay per tap (tPLH/tPHL), ±2ns or ±3% accuracy, TTL/CMOS-compatible I/O, and 17mA typical supply current at +25°C. It operates from -40°C to +85°C on +5.0V ±5% supply and drives up to ten 74LS loads per tap. Used in clock synchronization and digital system timing alignment.

For engineers reviewing the MXD1005SA075 datasheet, MXD1005SA075 pinout, MXD1005SA075 application, or MXD1005SA075 equivalent, this page delivers verified electrical parameters, µMAX package layout, tap-specific delay behavior, temperature/voltage stability data, and direct alternatives for timing-critical PCB designs requiring deterministic propagation delays.

Technical Context

The MXD1005SA075 implements a monolithic silicon delay chain with five equally spaced taps-TAP1 through TAP5-each delivering 20%, 40%, 60%, 80%, and 100% of the nominal 75ns delay relative to the input (IN). All delays track unilaterally with temperature and supply voltage shifts, preserving inter-tap timing relationships.

It features leading- and trailing-edge accuracy measured at 1.5V thresholds, supports 50% duty cycle inputs up to 10MHz, and maintains stable operation under load conditions matching 74F04 gate inputs. No internal compensation circuitry is required-the delay variation is inherently monotonic across VCC (4.75V–5.25V) and temperature (-40°C to +85°C).

Key Specifications

Pinout & Package

MXD1005SA075 is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), pin-compatible with 8-pin SO and DIP variants. The µMAX footprint reduces board area by >60% versus SOIC while maintaining identical signal routing.

FAQ

What is the exact delay value per tap for MXD1005SA075?

The MXD1005SA075 provides five fixed delays: TAP1 = 15ns, TAP2 = 30ns, TAP3 = 45ns, TAP4 = 60ns, and TAP5 = 75ns, all referenced to the IN pin's 1.5V threshold crossing. These values are specified as tPLH and tPHL with ±2ns or ±3% tolerance, whichever is greater, and are guaranteed over -40°C to +85°C at +5.0V ±5% supply. The MXD1005SA075 achieves this via calibrated on-die delay chains-not programmable or adjustable.

Does MXD1005SA075 support both rising- and falling-edge triggered delays?

Yes, the MXD1005SA075 guarantees leading-edge (tPLH) and trailing-edge (tPHL) accuracy independently-both within ±2ns or ±3% tolerance. This dual-edge specification enables precise alignment of both clock and data strobes in bidirectional interfaces. The MXD1005SA075 uses symmetric internal circuitry to ensure matched propagation for rising and falling transitions, validated per Maxim's Test Conditions (1.5V threshold, 50Ω source, 3ns max rise/fall time).

Can MXD1005SA075 drive modern CMOS loads like 74LVC or FPGA I/O directly?

Yes, the MXD1005SA075 outputs are TTL/CMOS-compatible with VOH ≥4.0V (at VCC = 4.75V, IOH = -1mA) and VOL ≤0.5V (at VCC = 4.75V, IOL = 12mA), meeting 74LVC and most FPGA input thresholds. It drives up to ten 74LS loads, which translates to ~20–25 pF capacitive load-well within safe operating range for LVC and 3.3V FPGA I/O. The MXD1005SA075 does not require series termination for typical PCB trace lengths under 10 cm.

How does temperature affect delay matching between taps in MXD1005SA075?

Temperature changes cause all taps in the MXD1005SA075 to shift delay unilaterally-meaning TAP1 through TAP5 slow down or speed up together. For example, at -40°C, all delays increase by ~1.5% relative to +25°C; at +85°C, they decrease by ~1.2%. This preserves inter-tap spacing (e.g., TAP2–TAP1 remains ~15ns), making the MXD1005SA075 ideal for applications requiring stable relative timing, such as phased clock generation or multi-stage pipeline control.

Is MXD1005SA075 pin-compatible with DS1005-75?

No, MXD1005SA075 is not pin-compatible with DS1005-75. The MXD1005SA075 uses an 8-pin µMAX package with IN, TAP1–TAP5, VCC, and GND on pins 1–8 respectively. The DS1005-75 uses a 14-pin DIP with different pin assignments, including unused pins and separate VCC/GND pairs. While functionally similar, the MXD1005SA075 requires PCB layout revision to replace DS1005-75-though its smaller size and lower power offer compelling system-level benefits.
