f-p electronics the FP2800A decoder driver is a 40 pin integrated circuit which provides the decoding to select one of 28 high current driver outputs for sinking and sourcing current. a complementary driver is available for bridge output applicatlons. the cm os compatible data inputs are grouped to allow one of four 7 -segment displays to be add ressed. a data pin sets the output to source or sink moda and the output is activated for the duration ot an enable signal. features: . operates up to 27.3 volts d.c. . source and sink up to 370 ma . law saturation devices . internat clamping diodes for inductive loads . microprocessor compatible inputs applications: . driving 1.
