DESCRIPTION
The L9308 is a monolithic interface circuit with dif-
ferentialinput comparator and open collector output
able to sink current specifically to drive lamps, re-
lays, d.c. motors, electro valves etc.
Particular care has been taken to protect the device
against destructive failures - short circuit of outputs
to VS, SOA protection, supply overvoltage.

ORDERING NUMBER : L9308
A built in thermal shut-down switches off the device
when the IC’s internal dissipation becomes too high
and the chip temperature exceeds the security
threshold.
The input comparatorhysteresis increases the inter-
face’s noise immunity allowing the correct use in
critical environments as automotive applications.
