SINGLE SUPPLY VOLTAGE (3.5V up to 18V)
Powerdip (8 + 8)
ORDERING NUMBER : L9305A
DESCRIPTION
The L9305A is a monolithic interface circuit with dif-
ferential input comparator and open collector output
able to sink high current specifically to drive relays,
lamps, d.c. motors.
Particular care has been taken to protect the device
against destructive failures - short circuit of outputs
to V
S
, output overvoltages, supply overvoltage.
BLOCK DIAGRAM
A built in thermal shut-down switches off the device
when the IC’s internal dissipation becomes too great
and the chip temperature exceeds a set security
threshold.
A hysteresis input comparator increases the interfa-
ce’s noise immunity, allowing the correct use also in
critical environments as automotive or industrial ap-
plications.
