DG202CSE+T

The DG202CSE+T is a quad SPST CMOS analogue switch in 16 pin NSOIC package. This normally open analogue switch will not latch up if power supplies are disconnected and input signals are still connected. The DG202 is similar to DG201 except for inverted control inputs. The device has break before make switching, as well as essentially constant on-resistance over the analogue signal range. It conducts current in either direction and adds no offset to the output signal. The DG202CSE+T has a maximum turn-off time of 450ns and maximum turn-on time of 600ns. The device consumes significantly low power by making it better suited for many applications. It is used in analogue multiplexers, programmable gain amplifiers, automatic test equipments, communications systems, PBX system, PABX system and sample/hold circuits.
