additional functionality while reducing ASIC design risk. The
ISL54056 is offered in small form factor package, alleviating
board space limitations.
The ISL54056 consists of four SPDT switches. It is configured
as a dual double-pole/double-throw (DPDT) device with two
logic control inputs that control two SPDT switches each. The
configuration can be used as a dual differential 2-to-1
multiplexer/demultiplexer. The ISL54056 is pin compatible
with the NLAS3799 and NLAS3799L.
