DESCRIPTION
The ISO518 is an 8-channel, isolated, bidirectional
digital coupler based on the Burr-Brown capacitive
barrier technology.
The ISO518 is designed with input and output buffers
for ease of integration into a µP bus system. All data
pins are I/O under the control of the TX pins. Input
and output buffers are controlled by the latch enable
pins. This feature of the ISO518, which allows mul-
tiple access to a data bus, requires extra circuitry when
using an alternative solution.
The ISO518 will transfer an 8-bit word at rates up to
2Mwords/s without the skew problems associated in
implementing this function with optocouplers. The
ISO518 is available in 24-pin PDIP or 24-pin Gull
Wing packages. Both are specified for operation from
–40°C to +85°C.

Data Bus A. The logic levels on these pins are transmitted
to, or received from the corresponding pins on data bus B.
Data Bus B. The logic levels on these pins are transmitted
to, or received from the corresponding pins on data bus A.
Latch Enable A. Latch enable signal for the A data buffer.
Latch Enable B. Latch enable signal for the B data buffer.
Transmit/Receive Control for Side A.
Transmit/Receive Control for Side B.
NOTES: (1) In transmit mode (TX/RX = 1), a logic 0 (LOW) will latch the input
buffer data into the input register and initialize the transmission. A logic 0
(LOW) will latch the internal buffer data into the output register and prevent
any further changes in the output data. A logic 1 (HIGH) will pass the internal
buffer data to the output register and permit each new set of data to appear
as soon as available after transmission. (2) A logic 1 (HIGH) will set that side
to transmit mode and the same side’s data bus to input mode. A logic 0 (LOW)
will set that side to receive mode and the same side’s data bus to output mode.
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
