will receive datawhen enable G is active (low).
In the isolation mode (enable G high), ”A” data
may be stored in one register and/or ”B” data
may be stored in the other register. When an
output bus is disabled, the input bus is still
enabled and may be used to store and transmit
data. Only one of the two buses, A or B, may be
driven at a time.
It has same speed performance at 3.3V than 5V,
AC/ACT family, combined with a lower power
consumption.
All
inputs
and
outputs
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
