Uni-Directional  
ISOLATED DIGITAL COUPLERS  
DESCRIPTION  
FEATURES  
ISO508 is an 8-channel, isolated, digital coupler based  
on the Burr-Brown capacitive barrier technology. The  
ISO508 has additional circuitry to ensure DC accuracy  
and overcome the edge-sensitive nature of normal  
capacitive devices even on power-up conditions. The  
novel circuitry involved will restore the correct output  
after a transient interruption should that be necessary.  
LOW POWER CONSUMPTION:  
< 12mW per Channel Typ.  
1500Vrms ISOLATION:  
100% Tested by Partial Discharge  
ASYNCHRONOUS OR SYNCHRONOUS  
OPERATION  
DOUBLE BUFFERED DESIGN FOR  
EASY INTEGRATION INTO BUS-BASED  
SYSTEMS  
The ISO508 is designed with input and output  
buffers for ease of integration into a µP bus system.  
The output buffer has tri-state capability, and by  
the use of OE, the output data bus lines can be  
made to go high impedance. This feature of the  
ISO508, which allows multiple access to a data  
bus, requires extra circuitry when using an alterna-  
tive solution.  
TRI-STATE OUTPUTS  
24-PIN PDIP OR GULL WING PACKAGES  
2MWORDS/SEC TRANSFER RATE  
1µSEC TRANSIENT RECOVERY  
ISO508 will transfer an 8-bit word at rates up to  
2Mwords/s without the skew problems associated  
in implementing this function with optocouplers.  
The ISO508 is available in 24-pin PDIP or 24-pin  
Gull Wing packages. Both are specified for opera-  
tion from –40°C to +85°C.
