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
碌P
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
鈥?0擄C to +85擄C.
