Description

4_IN

The IL715, IL716 and IL717 series of 4–channel digital isolators

provide the designer with the most compact isolated 5V logic

devices yet available. These isolators are packaged in three

options: IL715 with four unidirectional channels, IL716 with

two channels in one direction and two channels in the opposite

direction, and the IL717 with three channels in one direction and

one channel in the other direction. All these devices are

fabricated with patented* IsoLoop^®technology giving them

excellent transient immunity specifications. The symmetric

magnetic coupling barrier gives these isolators a propagation

delay of only 10 ns and a pulse width distortion of 2 ns. Devices

are 100% high voltage tested to guarantee barrier integrity.

Electrostatic Discharge Sensitivity

This product has been tested for electrostatic sensitivity to the limits stated in the specifications. However, NVE recommends that all

integrated circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could

range from performance degradation to complete failure.

Notes:

1. Absolute Maximum ambient operating temperature means

the device will not be damaged if operated under these

conditions. It does not guarantee performance.

2. PWD is defined as | t_PHL– t_PLH|. %PWD is equal to the

PWD divided by the pulse width.

3. t_PSKis equal to the magnitude of the worst case difference in

t_PHLand/or t_PLHthat will be seen between units at 25 C.

4. CM_His the maximum common mode voltage slew rate that

can be sustained while maintaining V_O> 0.8 V_DD. CM is

the maximum common mode input voltage that can be ^L

sustained while maintaining V_O< 0.8 V. The common

mode voltage slew rates apply to both rising and falling

common mode voltage edges.

5. Device is considered a two terminal device:

pins 1–8 shorted and pins 9–16 shorted.

Application Notes:

Power Consumption

Data Transmission Rates

The IsoLoop family of devices achieves its low power

consumption from the manner by which it transmits data

across its isolation barrier. By detecting the edge transitions

of the input logic signal and converting this to a narrow

current pulse which drives the isolation barrier, the isolator

then latches the input logic state in the output latch. Since

the current pulses are narrow, about 2.5 ns wide, the power

consumption is independent of mark-to-space ratio and

solely dependent on frequency. This has obvious advantages

over optocouplers whose power consumption is heavily

dependent on its on state and frequency.

The reliability of a transmission system is directly related to

the accuracy and quality of the transmitted digital

information. For a digital system, those parameters which

determine the limits of the data transmission are pulse width

distortion and propagation delay skew.

Propagation delay is the time taken for the signal to travel

through the device. This is usually different when sending a

low-to-high than when sending a high-to-low signal. This

difference, or error, is called pulse width distortion (PWD)

and is usually in ns. It may also be expressed as a

percentage:

Power Supply Decoupling

Maximum Pulse Width Distortion (ns)

PWD% =

x 100%

Signal Pulse Width (ns)

Both power supplies to these devices should be decoupled

with good quality 47 nF ceramic capacitors. For data

rates in excess of 10MBd, use of ground planes for both

GND1 and GND2 is highly recommended. Capacitors

should be located as close as possible to

e.g. for the IL717 @ 12.5 Mb

3 ns

80 ns

PWD% =

x 100% = 3.75%

the device.

This figure is almost 3x better than for any available

optocoupler with the same temperature range, and 2x better

than any optocoupler regardless of published temperature

range. The IsoLoop range of isolators including the IL717

surpasses the 10% maximum PWD recommended by

PROFIBUS, and will run at almost 35 Mb before reaching

the 10% limit.

Signal Status on Start-up and Shut Down

To minimize power dissipation, the input signals to the

IL715, IL716 and IL717 are differentiated and then latched

on the output side of the isolation barrier to reconstruct the

signal. This could result in an ambiguous output state

depending on power up, shutdown and power loss

sequencing. Therefore, the designer should consider the

inclusion of an initialization signal in his start-up circuit.

Propagation delay skew is the difference in time taken for

two or more channels to propagate their signals. This

becomes significant when clocking is involved since it is

undesirable for the clock pulse to arrive before the data has

settled. A short propagation delay skew is therefore critical,

especially in high data rate parallel systems, to establish and

maintain accuracy and repeatability. The IsoLoop range

of isolators all have a maximum propagation delay skew of

6 ns, which is 5x better than any optocoupler. The

maximum channel to channel skew in the IL717, IL716, and

IL715 isolators is only 3 ns which is 10x better than any

optocoupler.
