3-in-1 Silicon Delay Line
_______________General Description
The MXD1013 contains three independent, monolithic,
logic-buffered delay lines with delays ranging from
10ns to 200ns. Nominal accuracy is ±2ns for a 10ns to
60ns delay, ±3% for a 70ns to 100ns delay, and ±5%
for a 150ns to 200ns delay. Relative to hybrid solutions,
these devices offer enhanced performance and higher
reliability, and reduce overall cost. Each output can
drive up to ten standard 74LS loads.
The MXD1013 is available in multiple versions, each
offering a different combination of delay times. It comes
in the space-saving 8-pin µMAX package, as well as a
standard 8-pin SO and DIP. It is also offered in indus-
try-standard 16-pin SO and 14-pin DIP packaging,
allowing full compatibility with the DS1013 and other
delay-line products.

Specifications to -40°C are guaranteed by design, not production tested.
All voltages referenced to GND.
Measured with outputs open.
Guaranteed by design.
Pulse width and/or period specifications may be exceeded, but accuracy is application sensitive (i.e., layout, decoupling, etc.).
V
CC
= +5V at +25°C. Typical delays are accurate on both rising and falling edges within ±2ns for delays from 10ns to
60ns, within ±3% for delays from 70ns to 100ns, and within ±5% for delays from 150ns to 200ns.
Note 7:
The
Part Number and Delay Times
table provides typical delays at +25°C with V
CC
= +5V. The delays may shift with tem-
perature and supply variations. The combination of temperature (from +25°C to 0°C, or +25°C to +70°C) and supply varia-
tion (from 5V to 4.75V, or 5V to 5.25V) could produce an additional typical delay of ±1.5ns or ±3%, whichever is greater.
Note 8:
All output delays tend to vary unidirectionally with temperature or supply voltage variations (i.e., if OUT1 slows down, all
other outputs also slow down).

__________ Applications Information
Supply and Temperature
Effects on Delay
Over the specified range, the MXD1013’s delays are
typically 2% accurate. Variations in supply voltage may
affect the MXD1013’s fixed output delays. Supply volt-
ages beyond the specified range may result with larger
variations. Although there might be a slight variance in
delays over temperature, the MXD1013 is internally
compensated to maintain its nominal values.
Board Layout Considerations
Bypass the MXD1013 with a 0.1µF capacitor to mini-
mize the impact of high-speed switching on the power
supply. The power supply must be able to deliver the
required switching currents for proper operation.
It is advisable to minimize trace lengths in order to
reduce board capacitance as well as the traveling dis-
tance between devices. Sockets and wire-wrapped
boards increase capacitance and should be avoided.
Loading Effect on Delay Lines
Capacitive loads increase delay times as they increase
the rise and fall times of the delay lines. Other logic
devices increase the capacitance at the output of the
delays, which can affect device performance.
