 Description
The DIO31308 is a general-purpose CMOS analog
switch. The device supports bidirectional analog and
digital signals on the source and drain pins ranging
from GND to VCC. The DIO31308 device has an
internal injection current control feature that allows
signals on disabled signal paths to exceed the supply
voltage without affecting the signal of the enabled
signal path.
Additionally, the DIO31308 device does not have an
internal diode path to the supply pin, which eliminates
the risk of damaging components connected to the
supply pin or providing unintended power to the
supply rail. All logic inputs have 1.8 V logic
compatible thresholds, ensuring both TTL and CMOS
logic compatibility when operating with a valid supply
voltage. Fail-safe logic circuitry allows voltages on the
control pins to be applied before the supply pin,
protecting the device from potential damage.
The DIO31308 is available in TSSOP-16 and QFN-16
package. It is specified over ambient temperature
range of -40°C to 125°C, which meets the
requirements of applications.
