Description
The 6N137, HCPL-26XX/06XX/4661, HCNW137/26X1 are optically coupled gates that combine a GaAsP light emit­ting diode and an integrated high gain photo detector. An enable input allows the detector to be strobed. The output of the detector IC is an open collector Schottky­clamped transistor. The internal shield provides a guar­anteed common mode transient immunity speci cation up to 15,000 V/µs at Vcm=1000V.
This unique design provides maximum ac and dc circuit iso­lation while achieving TTL compatibility. The optocoupler ac and dc operational param e ters are guaranteed from ­40°C to +85°C allowing troublefree system performance.
Functional Diagram
A 0.1 F bypass capacitor must be connected between pins 5 and 8.

Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew
Propagation delay is a  gure of merit which describes how quickly a logic signal propagates through a sys­tem. The propaga tion delay from low to high (t
) is the
PLH
amount of time required for an input signal to propagate to the output, causing the output to change from low to high. Similarly, the propagation delay from high to low (t
) is the amount of time required for the input signal
PHL
to propagate to the output causing the output to change from high to low (see Figure 8).
Pulse-width distortion (PWD) results when t
PLH
and t
PHL
di er in value. PWD is de ned as the di erence be­tween t
PLH
and t
and often determines the maximum
PHL
data rate capa bil ity of a transmission system. PWD can be expressed in percent by dividing the PWD (in ns) by the minimum pulse width (in ns) being transmitted. Typi­cally, PWD on the order of 20-30% of the minimum pulse width is tolerable; the exact  gure depends on the par­ticular application (RS232, RS422, T-l, etc.).
Propagation delay skew, t
, is an important parameter to
PSK
consider in parallel data appli ca tions where synchroniza­tion of signals on parallel data lines is a concern. If the parallel data is being sent through a group of optocou­plers, di er ences in propagation delays will cause the data to arrive at the outputs of the optocouplers at di er­ent times. If this di erence in propagation delays is large enough, it will determine the maximum rate at which parallel data can be sent through the optocouplers.
puts of a group of optocouplers are switched either ON or OFF at the same time, t the shortest propagation delay, either t longest propagation delay, either t

, and the
parallel data transmission rate. Figure 20 is the timing diagram of a typical parallel data application with both the clock and the data lines being sent through opto­couplers. The  gure shows data and clock signals at the inputs and outputs of the optocouplers. To obtain the maximum data transmission rate, both edges of the clock signal are being used to clock the data; if only one edge were used, the clock signal would need to be twice as fast.
Propagation delay skew repre sents the uncertainty of where an edge might be after being sent through an opto coupler. Figure 20 shows that there will be uncer­tainty in both the data and the clock lines. It is important that these two areas of uncertainty not overlap, other­wise the clock signal might arrive before all of the data outputs have settled, or some of the data outputs may start to change before the clock signal has arrived. From these considera tions, the absolute minimum pulse width that can be sent through optocouplers in a parallel appli­cation is twice t
. A cautious design should use a slightly
PSK
longer pulse width to ensure that any additional uncer­tainty in the rest of the circuit does not cause a problem.
Propagation delay skew is de ned as the di erence be­tween the minimum and maximum propagation delays, either t
PLH
or t
, for any given group of optocouplers
PHL
which are operating under the same conditions (i.e., the same drive current, supply voltage, output load, and op­erating tempera ture). As illustrated in Figure 19, if the in-
